Examples Questions of Square Pyramid

Example 1: Find the square pyramid side length, radius, slant height, lateral surface area, base surface area, total surface area, and volume? If the pyramid lateral edge length is 35 m, height is 29 m.

Solution:

Given that,

Square Pyramid lateral edge length e = 35 m

Height of the pyramid h = 29 m

Side length a = √[2(e² - h²)]

a = √[2(35² - 29²)]

a = √[2(1225 - 841)] = √(2 * 384)

a =√768 = 27.71 m

Slant height s = √[(1/2) (e² - h²)]

s = √[(1/2) (35² - 29²)]

s = √[(1/2) (1225 - 841)]

= √[(1/2) (384)]

= √192 = 13.85 m

Volume V = (2h/3)(e² - h²)

V = ((2 * 29/3)(35² - 29²)

= (58/3)(1225 - 841)

= 19.33 * 384 = 7,424 m³

Lateral surface area L = a√(a² + 4h²)

L = 27.71√(27.71² + 4 * 29²)

= 27.71√(767.84 + 4 * 841)

= 27.71√(767.84 + 3,364)

= 27.71 * √4,131.84

= 27.71 * 64.27 = 1,780.92 m²

Radius r = a / 2

r = 27.71 / 2 = 13.85 m

Base surface area B = 2(e² - h²)

B = 2(35² - 29²)

= 2(1225 - 841)

= 2(384) = 768 m²

Total surface area A = a√(a² + 4h²) + 2(e² - h²)

A = 768 + 1,780.92 = 2,548.92 m²

∴ Square pyramid side length is 27.71 m, the radius is 13.85 m, height is 29 m, slant height is 13.85 m, the base surface area is 768 m², the lateral surface area is 1,780.92 m², the volume is 7,424 m³, lateral edge length is 35 m, and total surface area is 2,548.92 m².

Example 2: Compute the square pyramid slant height, radius, total surface area, lateral surface area, volume, lateral edge length, base surface area, and total surface area. If the pyramid height is 12 cm, side length is 6 cm.

Solution:

Given that,

Square pyramid height h = 12 cm

Pyramid side length a = 6 cm

Volume V = (1/3)a²h

V = (1/3) * 6² * 12

= (1/3) * 36 * 12 = 432 / 3

= 144 cm³

Lateral Surface Area L = a√(a² + 4h²)

L = 6√(6² + 4*12²)

= 6√(36 + 4*144) = 6√(36 + 576)

= 6√612 = 6 * 24.73 = 148.43 cm²

Base Surface Area B = a²

B = 6² = 36 cm²

Total Surface Area A = L + B = a(a + √(a² + 4h²))

A = 36 + 148.43 = 184.43 cm²

Lateral Edge Length e = √(h² + (1/2)a²)

e = √(12² + (1/2)6²)

= √(144 + (1/2)36)

= √(144 + 18) = √162

= 12.72 cm²

Radius r = a / 2

r = 6 / 2 = 3 cm

Slant Heigh s = √(h² + (1/4)a²)

s = √(12² + (1/4)6²)

= √(144 + (1/4)36)

= √(144 + 9) = √153

= 12.36 cm²

∴ Square pyramid side length is 6 cm, the radius is 3 cm, height is 12 cm, slant height is 12.36 cm, the base surface area is 36 cm², the lateral surface area is 148.43 cm², the volume is 144 cm³, lateral edge length is 12.72 cm², and total surface area is 184.43 cm².

FAQs on Pyramid Calculator

1. What are the properties of a square pyramid?

The square pyramid properties are given here:

Base is square

It has 8 edges, 5 faces, and vertices.

The 4 side faces are triangles.

2. What is the square pyramid face area formula?

Square pyramid face area formula is face area = (a/2)[√((a² / 4) + h²). Where a is the side length, h is the height.

3. Find the total surface area of a regular pyramid having a square base where the length of each edge of the base is equal to 8 m, the slant height of a side is 15 m and the altitude is 18 m?

Perimeter of sqaure is P = 4a = 4 * 8 = 32 m

Area of sqaure A = a² = 8² = 64 m²

Total surface area = ½ * 32 * 15 + 64 = 304 m².
