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

${ \huge{ \purple{Answer:}}}$

__________________________

Length (l) = 7 cm

Breadth (b) = 11 cm

Height (h) = 13 cm

Total Surface Area = 2(lb+bh+hl)

= 2(7×11+11×13+13×7)

= 2(77+143+91)

= 2×311

Total Surface Area = 622 cm²
