Answer:
d
Step-by-step explanation:
Answer:
c = 40 and d = 76
Step-by-step explanation:
this is going to take me a long time to explain but here we go
so you need to do 180 - 116 and get 64.
then create a equation that is like this 7y + 6 + 4y + 64 = 180
when you solve it you get y = 10
then plug in 10 in for y in 4y. and you get 40 for c
do the same for d and you will get 76

Considering that the trench is modeled by a rectangular prism, the volume that was removed is 1776 cubic feet.
The volume of a <u>rectangular prism of length l, width w and height h</u> is given by:

In this problem, we want the measures in feet, and considering that 1 feet is 12 inches:
- The length is of 102' 6''(102 feet and 6 inches), hence
.
- The width is of 5' 4'', hence
.
- The depth(height) is of 3' 3'', hence
.
Then:

The volume that was removed is 1776 cubic feet.
