Question

The dimension of a cuboid are 7cm, 11cm & 13cm, The total surface area is ​

Answer 1

Answer:

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

= 2(7*11+11*13+13*7)

=2(77+143+91)

=2(311)

=622 cm^2

Answer 2

Question:-

• The dimension of a cuboid are 7cm, 11cm & 13cm, The total surface area is

______________________________

Given:-

• The dimension of a cuboid are 7cm, 11cm & 13cm.

______________________________

To Find:-

• The total surface area is

______________________________

Formula Used:-

Total Surface Area of a Cuboid (TSA) = 2 (lw + wh + lh) square units

______________________________

Solution:-

• total surface area is 622 cm²

______________________________

Explanation:-

Surface area :

= 2 ( 7 × 11 + 11 × 13 + 7 × 13 )

= 2( 77 + 143 + 91 )

= 2 × 311

= 622 cm²
