Question

Hallie can use the equation p = 4l + 4w + 4h to determine the sum of the lengths of the edges of a rectangular prism. She begins to solve the equation for h but runs out of time. Her partial work is shown below:

p = 4l + 4w + 4h

= l + w + h
h = –
Which expression should follow the subtraction in Hallie’s equation?

Answer 1

h = p - l - w

Explanation:

p = 4l + 4w + 4h Divide l, w, and h by 4

p = l + w + h Set the equation equal to h

h = p - l - w

Answer 2

A just did it on edge<3
