Four identical cubes of edge `5 cm` are placed side by side to form a cuboid of length `20 cm`. Find the total surface area and volume of the cuboid.

Text Solution

Verified by Experts

The correct Answer is:
450 sq.cm, 500 cubic cm
Edge of each cube `5 cm`
Since four identical cubes are placed side by side to form a cuboid.
Length of the cuboid `=20 cm`
Breadth of the cuboid `=5cm`
Height of the cuboid = `5cm`
Total surface area of the cuboid
`2(20xx5+5xx5+5xx20)`
`2(100+25+100)=2(225)=450sq.cm`
Volume of the cuboid `=20xx5xx5=500 cm `.
