Question

The equation below shows the total volume (V), in cubic units, of 4 identical boxes with each side equal to s units: V = 4s3 If s = 2.5 units, what is the value of V?

25 cubic units
30 cubic units
62.50 cubic units
156.25 cubic units

Answer 1

Hello!
----
So, If S= 2.5,
----
You multiply 2.5 x 4 and get 10!
----
Then, multiply 10 x 3 and get 30!
----
30 will be your answer.

Answer 2

Answer: 62.50 Cubic Units (NOT 30)

Explanation:

each side of a box is s = 2.5 units

volume of one box is length * width * height

since its a cube all sides are equal

volume of one box = s³ = 2.5³

since there are 4 boxes,

total volume V = 4s³

V = 4 * 2.5³ = 4 * 15.625

= 62.50
