amy said there are three cubic feet in a cubic yard explain why amy is incorrect

Answer 1

1 yd = 3 ft

Answer 2

HI the problem is [2/3- 1/3] times 5/8

I don't understand it thank you if you can help.

Answer 3

well, just work from the inside out
2/3 - 1/3 = 1/3 so, what you have without the brackets is
1/3 * 5/8 = 5/24
