Question

Find the capacity of the tanks with the following internal dimensions. Express the capacity in cubic metres and litres in each case :

Length = 3 m 20 cm

Breadth = 2 m 80 cm

Depth = 1 m 50 cm

Answer 1

Given that:-

Length (L)= 3 m 20 cm=3.2 m

Breadth (B)= 2 m 80 cm=2.8 m

Depth (H)= 1 m 50 cm=1.5 m

So, the tank must be cuboidal in shape.

We have to find its capacity/volume.

$\bigstar\;\;\sf{We\:know\: that:\boxed{\sf{Volume\: of \:a\: cuboid=L×B×H}}}$

So, V=3.2×2.8×1.5

V=13.44 m³

We know that 1 m³=1000 litres

So, 13.44 m³=(1000×13.44) litres

=13440 litres

Answer 2

Solutions :-

Given :
Length = 3 m 20 cm = 3.20 m
Breadth = 2 m 80 cm = 2.80 m
Depth = 1 m 50 cm = 1.50 m


Find the volume of the tank :-

Volume of cuboid = lbh cubic units
= (3.20 × 2.80 × 1.50) m³
= 13.44 m³


We know that,
1 m³ = 1000 litres
13.44 m³ = 13.44 × 1000 = 13440 litres


Hence,
The capacity of the tanks = 13.44 m³ = 13440 litres
