Question

A lady builds 9cm length, 10cm width,3cm height box using 1 cubic cm cubes. what is the minimum number of cubes required to build the box?

Answer 1

2700 cubes because 9*10*30/1

Answer 2

The answer is 270 cubes

Given: A lady builds a box with dimensions

length 9cm,  width 10 cm and  height 3cm

The dimensions of cube used to built the box is 1 cubic cm cubes

To find: The minimum number of cubes required to build the box

Solution: Given dimensions of box = 9cm × 10cm × 3cm  

volume of box = length × width × height = 9cm × 10cm × 3cm = 270 cm³

volume of the cube used to build box = 1 cm³

Number of cubes used = volume of box/ volume of cube used

= $\frac{270 cm^{3} }{1 cm^{3} }$ = 270 cubes

∴ Number of cubes used = 270
