Question

Marcia needs to paint all the faces and the base of a model of a pyramid she made for her history project. The dimensions of the pyramid are shown. What is the total surface area of the pyramid?

135 in2
170 in2
240 in2
260 in2

Answer 1

The Answer is C

The Total Surface Area Of The Pyramid Is: 240

Answer 2

Think about this:

To find the surface area of a square, multiply two sides together.

To find the surface area of a triangle, multiply the base and height, then divide by 2.

So, you have four triangles with an area of 35 and a square with an area of 100.

This gives you 240 as your surface area.
