 Practice: Volume of Objects Composed of Right Rectangular Prisms Terms of Use    Contact Person: Donna Roberts  Directions: Read carefully. Note: Actual measurements may have been rounded to the nearest tenth.
The term "box" may be used to represent a right rectangular prism.

1.
A series of four small boxes are stacked as shown, resting atop one another. The bottom box measures length = 12", width = 12", and height = 3". Each box, above the bottom, will measure two inches less in both length and width than the box below it. Heights will remain the same. Find the total volume contained in all four boxes.

There are three right rectangular prisms all with a height of 4 cm. The first prism has a length of 5 cm. and a width of 9 cm. The second prism has a length twice that of the first prism, and a width of 5 more than the width of the first prism. The third prism has a length and width that are the sums of the lengths and widths of the first and second prisms, respectively.

10.
The larger the surface area of an ice cube the more heat it absorbs, so the faster it will melt. a) Find the volume of the standard ice cube.
Choose:
 1 cu.in. 6 cu.in. 4 cu.in. 3 cu.in.

b)
Find the volume of the rectangular ice prism.

Choose:
 1 cu.in. 6 cu.in. 3½ cu.in. 4½ cu.in.

c)
Find the surface area of the standard ice cube.

Choose:

 1 sq.in. 6 sq.in. 4 sq.in. 3 sq.in.

d)
Find the surface area of the rectangular ice prism.

Choose:

 8 sq.in. 7 sq.in. 6 sq.in. 3½ sq.in.

e)
Conclusion:
Choose:
 Both have the same volume and will melt at the same speed. Both have the same surface area and will melt at the same speed. The rectangular ice prism has a larger surface area and will melt faster. The standard ice cube has s smaller surface area and will melt faster.
