The volume of a cube is 27 in.³ how long is each side

3 inches

Explanation:

Through trial and error you can say something like

1^3 = 1*1*1 = 1

2^3 = 2*2*2 = 8

3^3 = 3*3*3 = 27

We stop here since we got a volume of 27

Or you could apply the cube root to 27 to get the answer we are after

The second portion with 1/3 as the exponent is handy for calculators that don't have a cube root button.

the answer is 11.2 (i know i’m late)

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
