Please help me and explain why. Its pretty simple but for some crazy reason I dont get it. Please help!! I ONLY need number 18. ONLY 18 nothing else

to find the volume you need to multiply the width length and height so you need to cube the side lengths. the side lengths of a cube are all equal

2 cubed is 8 and 2.5 cubed is 15.625

15.625 minus 8 is 7.625

so the volume of the second cube can hold 7.625 ft cubed more

to find this as a percentage you do 15.625 minus 8 and divide this by 8 and then times by 100

15.625 minus 8 is 7.625

7.625 divided by 8 is 0.953125

0.953125 times by 100 is 95.3125% or 95.3% to 3 significant figures.

d? maybe
