Question

How many wooden cubical blovks each of edge 12 cm can be cut out from a cuboidal block of dimensions 1.2 m× 0.72 m× 0.6 m .

Answer 1

Answer:

Step-by-step explanation:

edge of cube = 12 cm

dimensions of cuboidal block = 1.2m * 0.72m * 0.6m

                                                   = 120cm * 72cm * 60cm

no of cubes that can be cut out from cuboid = volume of cuboid / volume of one cube

= 120 * 72 * 60 / 12 * 12* 12

= 300

therefore 300 such cubical blocks can be cut out

Answer 2

300 wooden cubical blocks each of edge 12 cm can be cut out from a cuboidal block of dimensions 1.2 m× 0.72 m× 0.6 m .

Step-by-step explanation:

Length of block = 1.2 m

Breadth of block = 0.72 m

Height of block = 0.6 m

Volume of wooden block =$1.2 \times 0.72 \times 0.6$

Volume of wooden block =$0.5184 m^3$

Side of cubical blocks = 12 cm = 0.12 m

Volume of cube = $Side^3 = 0.12^3=0.001728 m^3$

No. of cubical blocks = $\frac{0.5184}{0.001728}=300$

Hence 300 wooden cubical blocks each of edge 12 cm can be cut out from a cuboidal block of dimensions 1.2 m× 0.72 m× 0.6 m .
