Question

NEED HELP 100 POINTS TO ANSWER ALL THREE QUESTIONS PLEASE

1. A rectangular prism has a length of 20 in, a width, of 2 in, and a height of 3 ¼ in. What is the volume of the prism? Question 1 options:

V = 25 ¼ in³
V = 130 ¼ in³
V = 120 ¼ in³
V = 130 in³




2. What is the volume of a box that measures 4 ft. long, 2 ½ ft. wide, and 2 ft. tall?

Question 2 options:

V = 16 ½ ft. ³


V = 20 ft. ³


V = 40 ft. ³

V = 8 ½ ft. ³





3. Find the volume of a right rectangular prism with the measurements: length is 5/4 in, width is 2 in, and height is 4 in.

Question 4 options:

V = 40 in³


V = 2 3/4 in³


V = 11/4 in³


V = 10 in³

Answer 1

1. V = 130 in³

Explanation:

1. You can find the volume of a rectangular prism with this formula:

( l • w )h

(20 • 2)3 1/4

=

130

And then add the label in³

Answer:

2. V = 20 ft³

Explanation:

2. A box is the same as a rectangular prism.

Use the same formula to find the answer.

(4•2 1/2)2

=

20

And then add the label ft³

Answer:

3. V = 10 in³

Explanation:

3. It doesn't matter if the rectangular prism is a "right" one so you can just use the same formula for a rectangular prism.

5/4 = 1 1/4 or 1.25

(1.25 • 2)2

=

10

And then add the label in³
