Eli made a wooden box in the shape of a rectangular prism the box has a lenght of 5 in, a width of 3 1/2 in, and a height of 7 in. What is the total area that he will paint?

154 sq.inch

Step-by-step explanation:

In this question, we are asked to calculate the area of a rectangular prism, given some measurements of the prism in question.

Mathematically, to calculate this , we employ a mathematical formula.

Let’s say the area of the prism is A.

Then mathematically;

A = 2(wl + hl + hw)

Where w, h and l represents the width, height and length respectively.

These have the following values as deduced from the question;

w = 3.5 in, h = 7 in and l = 5 in

We put these values accordingly in the formula to yield;

A = 2(17.5 + 35 + 24.5)

A = 2(77)

A = 154 sq.inch

$35.59 in pounds
