Question #7MultipleChoice Score:

The volume of a rectangular prism is 288 ft3. If its height is 6 feet and its length is 8 feet, what is its width?

A. 6 feet B. 8 feet C. 9 feet D. 12 feet

Question #8MultipleChoice

A cube is 6 feet on each side. What is its volume?

Q1: The answer is A. pyramid.

A pyramid has one polygon base. A prism has two polygon bases. A cone has one circular base. A cylinder has two circular bases.

Q6: The answer is false.

Surface area of a rectangular prism is:

A = 2 (wl + hl + hw)

A1 = 2 (4*5 + 6*5 + 6*4) = 2 (20+30+24) = 2*74 = 148

A2 = 2 (6*4 + 5*4 + 5*6) = 2 (24+20+30) = 2*74 = 148

Q7. The answer is A. 6 feet

The volume of rectangular prism is:

V = w * l * h

w = ?

So, just replace the knowing facts:

288 = w * 8 * 6

288 = w * 48

w = 288/48 = 6

Q8: The answer is 216 ft³

The volume of the cube is:

V = a³

Since a = 6, then:

V = 6³ = 216
