The Volume with unit cubes 2 exercise appears under the 6th grade (U.S.) Math Mission. This exercise practices finding the volumes of objects composed of a number of cubes.

Types of Problems

There is one type of problem in this exercise:

  1. Find the volume of the object: This problem gives a picture of a three-dimensional object composed of congruent cubes and the side length of the cubes. The user is asked to find the volume of the entire object and write the answer in the space provided.
    Vwuc2-1

    Find the volume of the object

Strategies

Knowledge of the volume formula for a cube is needed for this problem. Strong geometric visualization skills also help.

  1. The formula for the volume of a cube is the side length to the power of three (or side length "cubed.")
  2. With a calculator it is possible to write side length, enter, cubed, enter, and multiply by the number of cubes. This avoids having to use parentheses which can save time.

Real-life Applications

  1. When one fills up their vehicle with gas, the volume of gasoline in their gas tank helps to determine their purchase. Whether they fill up with gallons or liters of gasoline or diesel, the amount is a volume calculation. On a smaller scale, when one fills up a gas can to take to another vehicle or to use the gas to power another device, they again use volume for measuring.
