Question

Find the surface area and lateral surface area of a cuboid whose length, breadth and height are 12 CM, 13 CM and 15 CM respectively ​

Answer 1

Step-by-step explanation:

CSA of cuboid= 2(12+13)×15

2×25×15

750cm^2

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

2(12×13+13×15+12×15)

2(156+195+180)

2×531

726cm^2

Answer 2

Answer:

T.S.A =1062

L.S.A=570

Step-by-step explanation:

Given

length =12 cm

breadth =13cm

height =15 cm

formula to find surface area is

$2(lb + lh + bh)$

=2(12×13 + 12×15 + 13 ×15)

=1062cm^2

formula to find lateral surface area is

$2(l + b)h$

= 2 (12+13) 15

= 570 cm ^2
