Question

Find the capacity of the tanks with the following internal dimensions. Express the capacity in cubic meters and litres for each tank.

	Length	Breadth	Height
(i)	3 m 20 cm	2 m 90 cm	1 m 50 cm
(ii)	2 m 50 cm	1 m 60 cm	1 m 30 cm
(iii)	7 m 30 cm	3 m 60 cm	1 m 40 cm

Answer 1

	Length	Breadth	Height	Volume(v) = lbh
(i)	3 m 20 cm	2 m 90 cm	1 m 50 cm	v = 3.20 x 2.90 x 1.50 = 13.92m2.  = 13.92 x 1000 = 13920  Lts.
(ii)	2 m 50 cm	1 m 60 cm	1 m 30 cm	v = 2.50 x 1.60 x 1.3 = 5.2m2.  = 5.2 x 1000 = 5200 Lts.
(iii)	7 m 30 cm	3 m 60 cm	1 m 40 cm	v = 7.30 x 3.60 x 1.40 = 36.792m2.  =36.792 x 1000 = 36792 Lts.
