Question

the total surface area of a cuboid with dimension 10 cm × 6 cm × 5 cm is​

Answer 1

Total surface are of cuboid formula

=> 2(lb + bh + hl)

Let us take,

Length = 10 cm

Breadth = 6 cm

Height = 5 cm

Hence,

Area = 2(10*6 + 6*5 + 5*10)

Area = 2(140)

Area = 280cm^2

Answer 2

Answer :-

The total surface area of a cuboid with dimension 10 cm × 6 cm × 5 cm is 280 cm².

Solution :-

Dimensions of a cuboid = 10 cm * 6 cm * 5 cm

It means

Length of the cuboid (l) = 10 cm

Breadth of the cuboid (b) = 6 cm

Height of the cuboid (h) = 5 cm

We know that

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

= 2[10(6) + 6(5) + 10(5)]

= 2(60 + 30 + 50)

= 2(140)

= 280 cm²

Therefore the total surface area of a cuboid with dimension 10 cm × 6 cm × 5 cm is 280 cm².
