How do you find the volume of a solid figure made of unit cubes?

Back

The volume is found by counting the total number of unit cubes that fill the solid figure.

Front

What does it mean to count the number of cubes in a solid figure?

Back

Front

What is the formula to calculate the volume of a rectangular prism?

Back

Volume = length x width x height.

Front

How many unit cubes are in a solid figure that has a height of 2, a width of 3, and a length of 4?

Back

There are 24 unit cubes (2 x 3 x 4 = 24).

Front

What is a solid figure?

Back

A solid figure is a three-dimensional shape that has volume, such as a cube, sphere, or cylinder.
