Question

Find the volume , lateral surface area, total surface area of cuboid whose dimensions are l= 22cm,b=12cm and h=7.5

Answer 1

Heya friend,

Given that

Length = 22 cm

Breadth = 12 cm

Height = 7.5 cm

Solution


Volume of a cuboid = l × b × h

= 22 × 12 × 7.5

= 1,980 cm^3


L.S.A of a cuboid = 2(l + b) × h

= 2(22 + 12) × 7.5

= 2 × 34 × 7.5

= 510 cm^2


T.S.A = 2(lb + bh + hl)

= 2(22 × 12 + 12 × 7.5 × 7.5 × 22)

= 2(264 + 90 + 165)

= 2 × 519

= 1,038 cm^2



Thanks
