Question

The length breadth and height of a cuboid are 15cm, 10cm, and 20cm respectively . Find it's total surface area. ​

Answer 1

Length = 15 cm 

Breadth = 10cm

Height = 20cm

Total surface area of cuboid = 2× (lb + bh+ hl )

2×( 15×10 + 10×20 + 20×15)

2 × 650

1300

$1300 {cm}^{2}$

Answer 2

Answer:

l=15 b=10 h=20

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

2(15×10+10×20+20×15)

2(150+200+130)

2(480)
