Question

Ben made a model (shown below) of the square pyramid he plans to build when he grows up.
Find the surface area of the model.
height: 7
length and width: 10

Answer 1

The surface area of the model is 240 square unit.

Step-by-step explanation:

Perimeter of the base of the pyramid = 10 + 10 + 10 + 10 = 40

Height of the pyramid = 7

Area of the base = 10 x 10 = 100

Surface Area = $\frac{1}{2}\times 40\times 7 + 100$

                      = 140 + 100

                      = 240

Hence, the surface area of the model is 240 square unit.
