Free Online Surface Area of a Triangular Pyramid Calculator

Definition of a Triangular Pyramid:

To see a pyramid in actual life, simply consider the Great Pyramids of Egypt. A pyramid is a 3 dimensional form that has a polygon as its backside and triangles as its aspects, all assembly at a not unusual place factor. The triangular aspects are referred to as faces, and the lowest polygon is referred to as the base of the pyramid. The range of aspects the bottom polygon of a pyramid has is identical to the range of triangular faces at the pyramid. The not unusual place factor in which all of the triangular faces meet is referred to as the apex.

A pyramid may have any polygon as a base. We are going to pay attention on while that base is a triangle. A pyramid with a triangle as a base is a triangular pyramid. Since the bottom is a triangle and a triangle has 3 aspects, a triangular pyramid has 3 triangular faces. Triangular pyramids display up in architecture, art, design, and different areas.

There are varieties of triangular pyramids – ordinary and non-ordinary. A ordinary triangular pyramid has a base with aspects which might be identical in length. A non-ordinary triangular pyramid has a base with aspects which have exclusive lengths.

Volume Formula for a Triangular Pyramid

The extent of an item is how a great deal area there’s internal an item, so the extent of a triangular pyramid is how a great deal area there’s in the pyramid. The extent of a triangular pyramid may be determined the usage of the formula V = 1/3AH in which A = region of the triangle base, and H = peak of the pyramid or the gap from the pyramid’s base to the apex.

For example, if we had a triangular pyramid with peak 12 devices and the region of the bottom become 24 rectangular devices, then the extent of the pyramid could be V = (1/3)(24)(12) = ninety six cubic devices.

Surface Area Formula for a Triangular Pyramid:

The floor region of an item is the whole region of the item’s floor. Thus, the floor region of a triangular pyramid is the region of all of its faces and base combined. When we’ve an ordinary triangular pyramid, all the faces of the pyramid have the equal region. Therefore, the floor region of a ordinary triangular pyramid may be determined through including the region of the bottom to three instances the region of one of the faces. That is, SA = A + 3a in which A is the region of the pyramid’s base, and a is the region of one of the pyramid’s faces. And you can use this calculator by clicking the below link.

Square Pyramid Shape

h = height

s = slant height

a = aspect length

e = lateral part length

r = a/2

V = volume

Stot = general floor area

Slat = lateral floor area

Sbot = backside floor area

How to Use this Calculator:

Online calculator to calculate the floor location of geometric solids along with a capsule, cone, frustum, cube, cylinder, hemisphere, pyramid, square prism, sphere, round cap, and triangular prism

Units: Note that gadgets are proven for comfort however does now no longer have an effect on the calculations. The gadgets are in region to present a demonstration of the order of the outcomes which include ft., ft2 or ft3. For example, in case you are beginning with mm and you understand r and h in mm, your calculations will end result with V in mm3 and S in mm2.

Surface Area Formulas:

Capsule Surface Area

  • Volume = πr2((4/3)r + a)
  • Surface Area = 2πr(2r + a)

Circular Cone Surface Area

  • Volume = (1/3)πr2h
  • Lateral Surface Area = πrs = πr√(r2 + h2)
  • Base Surface Area = πr2
  • Total Surface Area
    = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

Circular Cylinder Surface Area

  • Volume = πr2h
  • Top Surface Area = πr2
  • Bottom Surface Area = πr2
  • Total Surface Area
    = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Conical Frustum Surface Area

  • Volume = (1/3)πh (r12 + r22 + (r1 * r2))
  • Lateral Surface Area
    = π(r1 + r2)s = π(r1 + r2)√((r1 – r2)2 + h2)
  • Top Surface Area = πr12
  • Base Surface Area = πr22
  • Total Surface Area
    = π(r12 + r22 + (r1 * r2) * s)
    = π[ r12 + r22 + (r1 * r2) * √((r1 – r2)2 + h2) ]

Cube Surface Area

  • Volume = a3
  • Surface Area = 6a2

Hemisphere Surface Area

  • Volume = (2/3)πr3
  • Curved Surface Area = 2πr2
  • Base Surface Area = πr2
  • Total Surface Area= (2πr2) + (πr2) = 3πr2

Pyramid Surface Area

  • Volume = (1/3)a2h
  • Lateral Surface Area = a√(a2 + 4h2)
  • Base Surface Area = a2
  • Total Surface Area
    = L + B = a2 + a√(a2 + 4h2))
    = a(a + √(a2 + 4h2))

Rectangular Prism Surface Area

  • Volume = lwh
  • Surface Area = 2(lw + lh + wh)

Sphere Surface Area

  • Volume = (4/3)πr3
  • Surface Area = 4πr2

Spherical Cap Surface Area

  • Volume = (1/3)πh2(3R – h)
  • Surface Area = 2πRh
Surface Area of a Triangular Pyramid Example:

Question:

Determine the floor region of a triangular pyramid whose apothem duration is five cm, facet duration is eight cm and slant peak is 10 cm.

Solution:

Apothem duration = five cm

Side duration = eight cm

Slant peak = 10 cm

Hence, the floor region of a triangular pyramid is one hundred forty rectangular units.
