Question

A cuboidal metal container is 8.4 m long, 80 cm wide, and 1.2 m deep. Find the weight of the metal if itweighs 0.20 kg per m³​

Answer 1

Dimensions of the box = 8.4 m × 0.8 m × 1.2 m

Density = 0.20 kg/m³

We know,

m = dV

And, volume of a cuboid = l × b × h

∴ m = (8.4 m × 0.8 m × 1.2 m)(0.2 kg/m³)

⇒ m = 8.064 × 0.2 kg

⇒ m = 1.6128 kg

Thus, the the box weighs 1.6 kgs.
