Question

find the volume and total surface area of cuboid whoes length is 3.5m,breadth is 2.6m and height is 0.9m.​

Answer 1

Step-by-step explanation:

Volume of a cuboid = length x breadth x height

Surface area = 2(l x b + l x h + b x h)

Length(l) = 3.5 m

Breadth(b) = 2.6 m

Height(h) = 0.9 m

Therefore,

Volume = l x b x h = 3.5 x 2.6 x 0.9 = 8.19 meter cube.

Surface area = 2(l x b + l x h + b x h) = 2(3.5 x 2.6 + 3.5 x 0.9 + 2.6 x 0.9)

                                                           = 2(9.1 + 3.15 + 2.34) = 14.59 meter square
