Question

A water tank in the form of a cuboid is 6 metre long 5 metre wide and 4.5 M deep find the capacity of the tank in litres is 1 metre cube is equal to 1000 litres​

Answer 1

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

1 m³ = 1000 liters

135 m³ = 135000 liters

So capacity of tank = 135000 liters

LSA of cuboid = 2h( l + b)

= 2 x 4.5 (6 + 5)

= 9 x 11 = 99 m²
