Question

if lenght, breadth and height of a cuboid are 15 cm, 12 cm and 5 cm respectively. find its surface area​

Answer 1

Answer:

length =15 cm

breadth =12cm

height= 5cm

surface area= 2(lb+bh+hl) = 2(180+60+75) = 2(315) = 630 cm²

Answer 2

Answer:

tsa of cuboid= 2*(lb+bh+lh)

Step-by-step explanation:

l=15

b=12

h=5

2*(15*12+12*5+15*5)

=> 2*(180+60+75)

=> 2*315

=> 630 cm squared
