Question

The length,breadth and height of a cuboid are in the ratio 3:4:6and its volume is 576 cm³ the whole surface area of the cuboid is

Answer 1

this is answer................

Answer 2

let the ratio be x
so the length breadth and hight =3x,4x,6x
volume =
$576cm {}^{2}$
2(lb+bh+hl)
volume =lbh

$3x \times 4x \times 6x = 576$
$72x = 576$

$x = 576 \div 72$
$x = 8$
$length = 3 \times 8 = 24$
$breadth = 4 \times 8 = 32$
$height = 6 \times 8 = 48$
$2(24 \times 32 + 32 \times 48 + 48 \times 24)$
$= 6912 \:$
