Question

5 cubes of size 3 cm are joined together to form of cuboid. find curved surface area of cuboid​

Answer 1

Answer:

Given,

Side of cube (a) = 3cm

Number of cubes (n) = 5

It is given that the 5 cubes are used to make a cuboid

Therefore,

Length of the cuboid (l) = 5(3) = 15cm

Breadth of the cuboid (b) = 3cm

Height if the cuboid (h) = 3cm

CSA of Cuboid = 2 ( l + b ) h

= 2 ( 15 + 3 ) 3

= 2 * 18 * 3

= 2 * 54

= 108 cm²
