Question

how many 4m cubes can be cut from a cuboid measuring 20m×12m×8m

Answer 1

$\huge\green{\mathfrak{Bonjour!!}}$

$n = \frac{20 \times 12 \times 8}{4 \times 4 \times 4} \\ \\ n = 5 \times 3 \times 2 \\ \\ n = 30$

$\underline\red{\mathfrak{Here ,\:n\:is\:number\:of\:cubes}}$

$<b>Hi !$

Here is your answer !!

_______________________________

Length of one side of cube = 4 m

Volume = S × S × S

=> ( 4 × 4 × 4 ) m³

_______________________________

Dimensions of a cuboid = 20 m × 12 m × 8 m

Volume = L × B × H

=> ( 20 × 12 × 8 ) m³

_____________________________

To Find :

Number of cubes can be cut from the cuboid

______________________________

SOLUTION :

$\bf \frac{volume \: of \: cuboid}{volume \: of \: cube} \\ \\ = > \bf \: \frac{( \: 20 \: \times \: 12 \: \times \: 8 \: ) \: {m}^{3} }{( \: 4 \: \times \: 4 \: \times 4 \: ) \: {m}^{3} } \\ \\ = > \bf \frac{20 \: \times \: 12 \: \times \: 8}{4 \: \times \: 4 \: \times \: 4} \\ \\ = > \bf 5 \: \times \: 3 \: \times \: 2 \\ \\ = > \bf30 \: cubes \: \: \: \: \: \: \: \: \: \: \: \: \: ans$
