Question

The density of aluminium is 2710kgm
Find the mass of an aluminium block with
dimensions 2 mx 15 mx1m.​

Answer 1

Given :-

• The density of aluminium is 2710kgm¯³. An aluminium block with dimensions 2 m x 1.5 m x 1 m.

To find :-

• Mass of aluminium block ?

Solution :-

• Density of aluminium = 2710kgm¯³

• Length of aluminium = 2m

• Breadth of aluminium = 1.5m

• Height of aluminium = 1m

Now,

→ Volume of aluminium

→ Length × breadth × height

→ 2 × 1.5 × 1

→ 3 m³

As we know that:-

→ Density = Mass/Volume

→ 2710 = Mass/3

→ Mass = 2710 × 3

→ Mass = 8130 kg

Hence,

Mass of aluminium is 8130 kg

Answer 2

Answer:

Given :-

The density of aluminium is 2710kgm¯³. An aluminium block with dimensions 2 m x 1.5 m x 1 m.
