Question

Find the total volume of each figure shown measured in cm (not to scale)

Answer 1

Explanation:

Answer 2

Let the thickness (or the depth) of the shown figure = t

Total surface area =
=
`2 (1)/(4) * 4 (3)/(4) + 3 (1)/(3) * ( 6 - 2 (1)/(4) )`
= 10.6875 + 12.5
= 23.1875

∴ Volume = 23.1875 t
