Question

find volume ,lateral surface area and total surface area of the cuboid whose dimensions are lenth =22cm breath = 12cm height = 7.5cm

Answer 1

volume of cuboid = l×b×h
= 22×12×7.5
= 264×7.5
= 1980 cubic cm
lateral surface area of cuboid = 2×(l+b)×h
= 2×(22+12)×7.5
= 2×34×7.5
= 68×7.5
= 510 cubic cm
total surface area of cuboid = 2(lb+bh+lh)
= 2×(22×12+12×7.5+22×7.5)
= 2 × (264+90+165)
= 2×519
= 1038 cubic cm
