Question

the length breadth and height of a cuboid are 20cm,15cm,10cm respectively. find its total surface area.

Answer 1

Answer:

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

=2(20*15+15*10+20*10)

=2(300+150+200)

=2(650)

=1300cm^2

Answer 2

Answer:

The answer is 1300cm²

Step-by-step explanation:

Now,

length of the cuboid= 20cm

breadth of the cuboid=15cm

height of the cuboid=10cm

total surface area (TSA) of the cuboid=2(lb+bh+hl)

                               TSA=2(20*15+15*10+10*20)

                                       =2(300+150+200)

                                       =2(650)

                                TSA=1300 cm²

Therefore,the TSA of the cuboid=1300 cm²
