Question

Please answer math questionS correctly for BRAINY

Answer 1

1. to find length of cube using volume: cubic root of volume so ∛3375 = 15 ft

  check 15^3 = 3375

2.  volume of cube = L^3 = 18^3 = 5,832 m^3

3. volume = 2 x 2 x 2 = 8cm

1cm = 10 mm

8 x 10 = 80 mm^3

Answer 2

Hello there,

1st attachment: 

So in order to find this answer. We need to know that in a CUBE there is L*W*H. Your answer would be A.) 1125 because when we do 1125 3 times (L*W*H). . . It give's us 3375.

2nd attachment:

Your answer would be D.) 5,832m³.

My reason I say this is because when you do 18 square root to 3. It will give you 5,832m³

3rd attachment:

Your correct answer would be 80mm³. So this is what I did. C wouldn't be the wrong answer because that answer is in "inches" and we want to find the answer in "mm³" So when we do 2*2*2. We get 8cm. We need to find the answer in "mm³" "8cm" converted in "mm³" would equal 80mm³.

Hope this helps.
