Question

find the total surface area of a cuboid whose length=12cm, breadth= 10cm and height=14cm​

Answer 1

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

2(12x10+10x14+14x12)

2(120+140+168)

2(428)

856cm square

Answer 2

Answer: 856 cm^2

Step-by-step explanation:

Given:

Length of a cuboid = 10 cm

Breadth of a cuboid = 12 cm

Height of a cuboid = 14 cm

We know that, Surface area of cuboid = 2 (lb + bh + hl) cm^2

= 2 (10×12 + 12×14 + 14×10)

= 2 (120 + 168 + 140)

= 2 (428) = 856 cm^2
