Question

Cade covered the outside of a box shaped like a rectangular prism with paper. The box is 3.5 feet long, 2.2 feet wide, and 4.1 feet high. What is the total surface area of this box?

Answer 1

The total surface area of this box is 62.14 square feet

Explanation:

Given:

Length = 3.5 feet

Width = 2.2 feet

Height = 4.1 feet

To Find:

The Surface area of the prism = ?

Solution:

The box is the shape of rectangular prism

Then the surface area of the prism = 2(lh +hw +wl)

Where

l is the length

w is the width

h is the height

Substituting the values

The surface area of the prism =
`2((3.5 * 4.1) +(4.1* + 2.2) +(2.2 * 3.5))`

The surface area of the prism = 2(14.35 + 9.02 + 7.7)

The surface area of the prism = 2(31.07)

The surface area of the prism = 62.14 square feet
