Question

Identify the lateral area and surface area of a regular square pyramid with base edge length 11 cm and slant height 15 cm, rounded to the nearest tenth.

Answer 1

The lateral and surface area of a square base pyramid with side length of 11 cm and slant height of 15 cm are 330 cm² and 451 cm².

Surface area of a pyramid

surface area = A + 1 / 2 ps

where

• A = area of the base
• p = perimeter of the base
• s = slant height

Therefore,

surface area = 11² + 1 / 2 × (11 × 4) × 15

surface area = 121 + 1 / 2 × 44 × 15

surface area = 121 + 330

surface area = 451 cm²

Lateral area of a square pyramid

lateral area = 1 / 2 ps

lateral area = 1 / 2 × 44 × 15

lateral area = 330 cm²

Answer 2

The surface area of the square pyramid is: 451 cm²

The lateral surface area of the square pyramid = 330 cm²

What is the Lateral Surface Area and Surface Area of a Square Pyramid?

Surface area = a² + 2al, where a is the base edge and l is the slant height.

Lateral Surface Area =  2al.

Given the following:

• a = 11 cm
• l = 15 cm

Surface area = a² + 2al = 11² + 2(11)(15)

Surface area = 451 cm²

Lateral Surface Area =  2al = 2(11)(15)

Lateral Surface Area = 330 cm²
