Question

Find the lateral surface area and the total surface area for the pyramid .

Answer 1

Lateral Surface Area: 56 in²

Total Surface Area: 81 in²

Explanation:

To find the lateral surface area, all we need to do is find the surface area for one of the lateral faces and then multiply it by 4.

`(1)/(2) *b*h`

`(1)/(2) *5*5.6=2.5*5.6=14`

Now the area of all the lateral faces:

14*4=56

The total surface area is the lateral area plus the base.

56+(5*5)=56+25=81
