word problem
13. A metallic cuboid with dimensions 64cm x 8cm x 8cm was melted and recast into a cube.
What is the length of the edge of the cube?​

Answer 1

so,

you have to equate volume of a cuboid and volume of a cube , you'll get the value of a and that is the length of the edge of the cube

volume of a cuboid = volume of a cube

lbh = a³

64×8×8 = a³

4096 = a³

16 = a

Therefore , length of the edge of the cube is 16 cm
