Question

A cuboidal box of dimensions 1m x 2m x 1.5 m is to be painted except its bottom .Calculate how much area of box has to be painted​

Answer 1

Answer:

Step-by-step explanation:

Length of cabinet(l)  = 2 m, Breadth of(b) = 1 m

Height of cabinet (h)= 1.5 m

 Surface area of cabinet= area of top + lateral surface area

= lb + 2(l+b)h

 Surface area of cabinet= lb + 2(l+b)h

= 2×1+2(2+1)×1.5

= 2+2(3)× 1.5

= 2+ 6 ×1.5

= 2+ 9

= 11 m²

Hence, the required surface area of cabinet is 11m²
