Question

A swimming pool is shaped like a big box with a length of 22 m, a
h depth of 3m, and a width of 12m. What is the volume of the
swimming pool?​

Answer 1

Answer:

Correct option is B)

The cross section of the swimming pool is a trapezium with parallel sides 1.5m and 3m (depth of both ends) and 40m (length of pool) as the ⊥ r distance between ∥ sides.

The width of pool 1.5m can be the length of  cross section.

Length of swimming pool=40m

Breadth of the pool=15m

Depth of the pool=1.5m and 3m

∴ Volume of the water=

​

[(1.5+3)×40]×15m

Capacity of water in litres =1350×1000litres   (1m

=1000litres)

                                          =1350000litres

Answer 2

Answer:

792 cubic meter

Explanation:

The swimming pool is a cuboid

The volume of cuboid is l

$l \times b \times h$

Therefore,

$22 \times 12 \times 3$

So answer is 792 cubic meter
