PLEASE HELP DUE TODAY DO A AND B PARTS PLEASE PLEASE HELP ME FIGURE OUT THE LENGTH 100 POINTS ​
aksik [14]

Answer:

Length A:  5 ft

Width B:  4 ft

volume = 88 ft³

Step-by-step explanation:

Length A:   8 - 3 = 5 ft

Width B:   8 - 4 = 4 ft

<u>Volume</u>

The easiest way to calculate the volume is to split the trough into two rectangular prisms. (imagine drawing a horizontal line from the internal corner of A and 4ft to the left 8ft side).

Volume of a rectangular prism = width x length x height

Volume of rectangular prism 1: B x 8 x 2 = 4 x 8 x 2 = 64 ft³

Volume of rectangular prism 2: 3 x 4 x 2 = 24 ft³

Total volume = 64 + 24 = 88 ft³
