Question

a cuboid of dimensions 15 12 and 6, how many cuboids are required to make perfect cube​

Answer 1

» Given

sides of a cuboid are 15cm, 12cm and 6cm

» To find

how many cuboids are required to make perfect cube

» Solution

$volume \: of \: cubiod = 15 \times 12 \times 6$

→ Volume of cuboid = 1080 cu. cm

Let the side of the cube formed with minimum number of cuboids = x

$Hence \: volume \: of \: the \: cube = {x}^{3} ( {cm}^{3)}$

Number of cubiods required = n * 1080

$= 108 \times 2 \times 5$ = 1080
