Question

Ima need help, I'm confused about this depth stuff ​

Answer 1

Depth is also referred as height.

Volume of the rectangular part = l b h

= 18 × 10 × 5

= 900 ft³

Volume of two semi circular parts = 4 / 3 π r³

= 4 / 3 × 5 × 5 × 5 × π

= 523.8 ft³

Total Volume of the figure = 1423.8 ft³

Answer 2

$v (total)= v(r \: p \: ) + v(c)$

$v(t) = lwh + \pi {r}^{2} h$

$v(t) =( 18 \times 10 \times 5 )+( 3.14 \times {5}^{2} \times 5)$

$v(t) = 900 + 392.50$

$v(t) = 1292.50 \: \: \: {ft}^{3}$
