Question

find volume and total surface area of sides of cuboid ,whose sides are :7,8,9
​

Answer 1

Step-by-step explanation:

$l = 7$

$b = 8$

$h = 9$

$volume = l \times b \times h$

$= 7 \times 8 \times 9$

$504$

$volume \: of \: the \: cuboid = 504 \: {cm}^{3}$

$total \: surface \: of \: cuboid = 2(lb + bh + lb)$

$2{(7 \times 8) \times( 8 \times 9) \times( 7 \times 9)}$

$2( 56 \times 72 \times 63)$

$2(254016)$

$508032$

Answer 2

Answer:

pls mark as brainlist it is right answer

Step-by-step explanation:

length= 7

breadth=8

height= 9

T.S.A= 2( 7×8) + (8×9) + (7×9)

= 2( 56) + (72) + ( 63)

= 2( 191)

= 382

Volume= 7×8×9 .......... L×B×H

= 504
