Question

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

Answer 1

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

Volume

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

Answer 2

• Length A=8-3=5ft
• Length B=8-4=4ft

Now volume of first prism

• L=8
• B=2
• H=3

$\\ \tt\hookrightarrow V=LBH$

$\\ \tt\hookrightarrow V=8(2)(3)$

$\\ \tt\hookrightarrow V=48ft^3$

For next prism

• L=5
• B=4
• H=2

$\\ \tt\hookrightarrow V=5(4)(2)=40ft^3$

• Total volume=40+48=88ft^3
