Question

I need some help on how to do this (two column proofs)

Answer 1

B =
`$ (3V)/(H) $`

Explanation:

The formula for the volume of the pyramid is given as:

V =
`$(1)/(3) $`Bh

Multiplying 3 on both sides, we get:

3V = Bh

Assuming the height, h is not zero, we divide throughout by h.

⇒
`$ (3V)/(h) = B $`

Hence, we arrive at a formula to find B = 3V/h.
