Question

Find the number of 6 cm cubes that can be cut out of a piece of wood with
dimensions 18 cm x 15 cm x 8 cm.

Answer 1

Answer:

10

Step-by-step explanation:

volume of each cube of edge 6cm =

${6}^{3}$

$= 216 \: {cm}^{3}$

volume of wood = 18×15×8

$= 2160 {cm}^{3}$

therefore no of cubes =

$\frac{2160}{216} \\ \\ 10$

Answer 2

Given:-

length of wood-18cm

breadth of wood-15cm

height of wood-8cm

therefore,

volume of cuboid = (18*15*8)cm³

Volume of cuboid= no. of cubes* volume of 1 cube.

18*15*8=n *6*6*6

so, n =(18*15*8)/(6*6*6)

n=10 {after solving }

HENCE, Total no. of cubes=10.
