Question

Find the surface area of the right rectangular prism shown below.
units?
2.5
-

Answer 1

46

Explanation

4 x 2 x 2 = 16

2.5 x 4 x 2 = 20

2 x 2.5 x 2 = 10

16 + 20 + 10 = 46

Answer 2

Answer: Surface area = 46 units²

Explanation:

The formula for determining the total surface area of a rectangular prism is expressed as

Surface area = 2LW + 2LH + 2WH

Where

L represents the length of the rectangular prism.

W represents the width of the rectangular prism.

H represents the height of the rectangular prism.

Looking at the diagram,

L = 4 units

W = 2.5 units

H = 2 units

Therefore,

Surface area = (2 × 4 × 2.5) + (2 × 4 × 2) + (2 × 2.5 × 2)

= 20 + 16 + 10

= 46 units²
