Question

find the total surface area and the lateral surface area of the cuboid whose dimension for length is equal to 20 CM breadth equal to 15 cm and height equal to 1 centimetre​

Answer 1

Answer:

Step-by-step explanation:

Given

Length(l)=20cm

Breadth(b)=15cm

Height(h)=1 cm

LSA of cubiod=2h(l+b)

=2*1(20+15)

=2(35)

=70 square cm

TSA of cubiod=2(lb+bh+lh)

=2(20*15+15*1+20*1)

=2(300+15+20)

= 2(635)

=1270 square cm
