Question

a cuboidal water tank is 7 metre long, 5 metre width and 4 metre deep. how many litres of water can it hold​

Answer 1

Answer:

Hi there !!

Length = l = 6 metres

Breadth = b = 5 metres

Height = h = 4.5 metres

Volume of cuboidal tank = 6 x 5 x 4.5 = 135 m³

WE know that ,

$\boxed{1m³\: =\:1000 liters}$

So ,

135 m³ = 135000 liters

Hence ,

Capacity of tank = 135000 liters

$\boxed{L.S.A of cuboid = 2( l + b)h}$

= 2 (6 + 5) x 4.5

= 9 x 11 = 99
