Question

the surface areas of a cuboid and a cube are equal. the dimensions of the cuboid are 18 m X 10 m X 9 m. find the side of a cube

Answer 1

HEY MATE
HERE IS YOUR ANSWER

surface area of cuboid = surface area of cube

$2\pi(l + b)h \: \: = 4l \times l \times l$
2× 3.14 × 9 ( 18 + 10 ) = 4l×l×l
6.28 × 9 (28)= 4 l×l×l
1582.56 ÷ 4 = l×l×l
395.64 = l× l×l

$\: \: \: \: \: \: \: \: l = 6 \sqrt{1009}$
therefore side of cube is
$6 \sqrt{1009}$
