Question

why should i have different units for volume and base area Ex: volume =
`in^(3)` Base Area =
`in^(2)` pyramid ^^^

Answer 1

Explanation:

Volume has three parameters and is three dimensional, thus needing a unit in the third power

In difference,

Area is two-dimensional and has only 2 parameters, thus needing a unit only in the second power

Answer 2

see below

Explanation:

Area is found by multiplying two dimensions together ( l*w)

Volume is found by multiplying three dimensions together ( l*w*n)
