Question

1. Find the surface area of the following figure.

Answer 1

Explanation:

Area of rectangle = length x width

Surface Area = sum of area of all surfaces

= sum of area of the 6 rectangles

= 5x10 + 5x10 + 5x3 + 5x3 + 3x10 + 3x10

= 190 square inches

Answer 2

190 in²

Here given :

• Length : 10 in

• Width : 5 in

• Height : 3 in

surface area of a rectangular prism:

2 ( Length * Width + Length * Height + Height * Width )

2 ( 10 * 5 + 10 * 3 + 3 * 5 )

2 ( 50 + 30 + 15 )

2 (95)

190 in²
