Lucky Charms are "magically delicious" and they happen to be Mia's favorite. I am designing a container that needs to hold at least 30 cubic inches of cereal so that Mia can have Lucky Charms with her at all times! If I design the box to measure 3 x 3 x 4 inches, will it be large enough to hold Mia's cereal?

• Yes, she will have room enough for 6 more cubic inch of cereal.

• No, she will be too small by 3 cubic inches.

• No, the surface area of the container is less than the surface area of the cereal.

• Yes, they have the exact same volume.

In a display at a museum, two planets have volumes of 16 cubic inches and 54 cubic inches. What is the ratio of their diameters?

Answer explanation

Diameters are a linear ratio, but you are given a volume ratio. Change the volume ratio to a linear ratio by cube rooting the volume ratio. If you don't know how to use the cube root function on your calculator be sure to ask!
