प्रश्न
A cuboid has total surface area of 372 cm2 and its lateral surface area is 180 cm2, find the area of its base.
उत्तर
We have,
Total surface area of the cuboid `(A) = 372 cm^2`
Lateral surface area of the cuboid `(A) = 180 cm^2`
Let,
a →Area of the base
We know that,
A = A' + 2a
`a = (A-A')/2`
`=(372-180)/2`
`=192/2`
=96 cm2
Area of the base is 96 cm2
