Question

The volume of cuboid is 3600 cm^3 and its hieght is 12 cm if the lenth and breath are in ratio 4:3,find its l and b

Answer 1

Answer:

Length=20cm.

Breadth=15cm.

Step-by-step explanation:

Volume= L×B×H.

Let the length be 4x and the breadth be 3x.(as the ratio is 4:3).

Volume= 4x×3x×12cm.

3600cm³= 4x×3x×12cm.

3600cm³/12cm=12x².

300cm²=12x².

x²=300cm²/12.

x²=25cm².

x=√(25cm²)

x=5cm.

So,

Length=4x=4×5cm=20cm.

Breadth=3x=3×5cm=15cm.
