Finding Volume of Regular and Composite Rectangular Prisms

When solving for composite volume, what are the steps you should take?

• Multiply all of the numbers together.

• Split the shape, find volumes, add together

• Split the shape, find volumes, multiply together

If the volume of Prism D is 120 ft.³ and the total volume is 140 ft.³, what is the volume of Prism C?

• 20 ft.³

• 15 ft.³

• 260 ft.³

• 16,800 ft.³

Select ALL numbers you would need for the dimensions (Length, Width, Height) of Prism C.

• 4 ft

• 2 ft.

• 5 ft.

• 1 ft.

• 8 ft.

In looking at this shape, no matter which way you cut it, which dimension would be the same?

• Height

• Width

• Length

What is the additive volume of this shape? (no need to label, just the numerical answer)

Select an expression you could use to solve for the total volume.

• (40 x 5 x 10) + (30 x 10 x 5)

• (30 x 20 x 30 x 40 x 5)

• (30 x 20 x 5) + (40 x 30 x 5)

True or False:

You always use EVERY number given to you on a shape as a part of your volume formulas.

• True

• False

Determine the additive volume.

• 9,600 cm³

• 460 cm³

• 220 cm³

• 380 cm³

Determine the additive volume (no need to label, just type the numerical answer).

No matter which way you cut this shape, you would NOT use both of the following numbers in your formulas:

• 2 cm

• 4 cm

• 10 cm

• 9 cm
