Question

Wooden box with dimensions 36cm×24cm×12cm is 2 cm find the weight of the wood if density of the wood is gram per metre cube

Answer 1

Answer:

Step-by-step explanation:

Given a thickness of 2 cm, we can the internal dimensions of the wooden box.

We have:

Length = 36 - (2 × 2) = 32 cm

Width = 24 - (2 × 2) = 20 cm

Height = 12 - (2 × 2) = 8 cm

The volume of the wood used is given by:

Volume = External volume - internal volume

Volume = (36 × 24 × 12) - (32 × 20 × 8) = 5248 cm³

Convert this to m³

= 5248/1000000 = 0.005248 m³

Density = mass/volume

mass = Density × Volume

mass = 100 × 0.005248 = 0.5248 grams

The weight of the wood is 0.5248 grams.
