Question

A cuboidal iron piece of dimensions 12 mx 4 m x 40 cm was melted into
cubicaliron pieces of side 4 cm each. How many pieces were made ?
ohimo of a cube of side 9 cm in cubic metres.how many bricks are required to build a Wall of height 2.88 and width 50 cm if the length of each brick is 12 cm and breadth is 10 cm ​

Answer 1

Answer:

Step-by-step explanation:

Cuboid Iron piece VOLUME = 12*4*0.4 = 19.2 $m^{3}$

Cube Iron pieces VOLUME  = 0.04 * 0.04 * 0.04        (since 1cm = 0.01m)

                                              = 0.000064  $m^{3}$

No. of cubes made = $\frac{volume of cuboid}{volume of cube}$

                                 = 19.2 $m^{3}$ / 0.000064  $m^{3}$

                                 = 300,000 cubes were made of Iron

Do the same of the second question. You will get the answer
