Topic : Surface Area of a Cuboid

Question : Find the Surface area of a Cuboid whose measurement is as shown in the figure.

cuboid with base 4cm

 

Solution :

Surface area of a cuboid = 2 (lh +bh) + 2lb

here length = l = 4

breadth = b = 4

height = h = 6

So surface area  = 2(4*6 + 4*6) + 2*4*4

= 2(24+24)+32

=2*48+32

=96+32

=128 Sqcm
