Question

The length, breadth and height of a cuboid are 12 cm, 11 cm and 10 cm. The difference between the total surface area and the lateral surface area of the cuboid is​

Answer 1

Answer:

total surface area of cuboid and lateral surface area are 494 and 251 respectively

Answer 2

Step-by-step explanation:

L=12cm , b=11cm , h=10cm

T.S.A of cuboid = 2(Lb+bh+hL)

=2(12×11+11×10+10×12)

=2(132+110+120)

=2(362)

= 724

L.S.A of cuboid =2h(L+b)

=2×10(12+11)

= 20× 23

=251

T.S.A of cuboid-L.S.A of cuboid

= 724 -251

= 473
