Question

find the surface area of the following cuboids length=12cm, breadth=10cm,height=15cm​

Answer 1

Answer:

900 square cm

Step-by-step explanation:

formula of surface area of cuboid = 2(lb+bh+lh)

• =2(12×10+10×15+12×15)
• = 2(120+150+180)
• = 2(450) =900

• surface area of cuboid is 900 square cm

Answer 2

Given,

Length=12cm,

Breadth=10cm,

Height=15cm.

Lateral surface area of cuboid : 2h(l+b)

= 2×15(12+10)

= 30(22)

= 660 cm^2

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

= 2(12×10+10×15+15×12)

= 2(120+150+180)

= 2(450)

= 900 cm^2
