Aright rectangular prism has a volume of 120 in. what is the new volume if the length, width and height are doubled?

We don't know what the dimensions are, but any numbers that have a sum of 120 will work. Let's use 3, 4, and 10.

3 x 4 = 12   10 x 12 = 120

But if you double each dimension:

6 x 8 = 48     48 x 20 = 960         To find how much the sums changed:

960 / 120 = 8     

The new volume is 8 times what it originally was! 960 in.

Sample Response: Henry will need a total of 15 pints of paint. The 3 pints of yellow were multiplied by 3 to get 9 total, so 2 pints of red would be multiplied by 3 to get 6 total.
