Question

Hi I am on my brother phone and need some help for a practice work sheet my mom gave me.

Answer 1

Surface are of prism is formed by

6 faces

1up,1down

2 lateral

2 front back

Then

Area up,down= 2x(10x5) = 2x50= 100 ft2

Areas lateral= 2x( 5x 1) = 10 ft2

Areas front back= 2x( 10x 1)= 20ft2

THEN total surface area is

Atotal= 100 ft2 + 10 ft2 + 20ft2 = 130 ft2

Then answer is

Surface area= 130 ft2
