Question

determine the total surface area of the cuboid whose sides are as follow 12.5cm,8cm and 2.5cm​

Answer 1

Answer:

2(12.5x8+8x2.5+12.5x2.5)

Step-by-step explanation:

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

Answer 2

Answer:

The total surface area of the cuboid whose sides are 12.5cm,8cm and 2.5cm​ is 75.625 sq. cm.

Step-by-step explanation:

Given, l = 12.5 cm, b = 8cm, h = 2.5 cm.

Find: The total surface area of the cuboid

Formula : Surface area of cuboid =2(lb + bh + hl)

= 2(12.5 × 8 + 8 × 2.5 + 12.5 × 2.5)

= 2(100 +20 + 31.25 )

= 2(151.25)

= 75.625 sq. cm

So, the total surface area of the cuboid is 75.625 sq. cm.
