Answer 1

your first question, the answer you chose isn't quite right :)
What you want to do to solve the question is to find the volume right?
To find the volume of the rectangular prism, you want to simply multiply the three sides together.
So V = length * width * height.
In your case V = 21.3 *8 * 10 = ?

Answer 2

you second question is CORRECT.
And again for the last one you want to remember that to calculate the volume of a rectangular prism, you want to multiply the length, width and height together.
So V = 7.2 *15 *5 = ?
