Question

a cuboid has the dimensions 16 cm*15 cm*12 cm is melted and cubes of side 2 cm are made out of the material so obtained find the number of cubes that were formed​

Answer 1

Answer:

$no \: of \: cubes = \frac{vlo \: ofcuboid}{vl \: of \: cube} \\ n = \frac{lbh}{ {a}^{3} } \\ n = \frac{16 \times 15 \times 12}{2 \times 2 \times 2} \\ n = 8 \times 15 \times 3 \\ n = 360$

360 cubes are formed

Answer 2

Answer:

volume of cube= 2^3=8

volume of cuboid=16×12×15=2880

no :of cubes =n

n×8=2880

n=2880/8=360
