Question

A cube is partially filled to the top with 4 mm3 of water. If the water is 1 mm high, what is the length of one side of the cube?
1 mm
2 mm
3 mm
4 mm

Answer 1

Answer:

b

Step-by-step explanation:

Answer 2

Your answer would be 2 mm. The formula for volume is v=lwh

You have the volume: 4mm. And you have the height: 1. Substituting the known values you have 4=(1)(x)(x).

Now the question is, 1 times what 2 numbers gives you 4? Well 2 does.

4=(1)(2)(2)

The rest of the numbers don't work. 1 times 1 times 1 is 1. 1 times 3 times 3 is 9. And one times 4 times 4 is 16.
