Question

a cube of side 12 cm is melted down up respired in to a cuboidal block of width 15cm and length 28cm. how high is the block​

Answer 1

4.2 cm is height approximately

Height is 12^3÷(28×15)

Answer 2

Height of the block is approximately 4.12 cm

Step-by-step explanation:

side of the cube = 12 cm

volume of the cube = a³

where a is the side of the cube

volume of cube = (12)³ =1728 cm³

length of  the cuboidal block = 15 cm

breadth of cuboidal block = 28 cm

volume of cuboidal block = volume of cube  = 1728 cm³

we have to find the height

volume of cuboidal block = L××B×H

1728 = 15×28 ×H

1728 = 420 ×H

H = $\frac{1728}{420}$

H= 4.12 cm  (approx)

hence,

Height of the block is approximately 4.12 cm
