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?
a) 730 b) 270 c) 720 d) 310
Read Solution (Total 8)
-
- 9*10*3=270
270/1=270
so 270 cubes are required to build the box

- cubes required=(10*10*10)-(9*10*3)=730
- 9 years agoHelpfull: Yes(0) No(1)
- 9*10*3=270
- 9 years agoHelpfull: Yes(0) No(0)
- 9*3*10=270
so total no of cubes required 270 - 9 years agoHelpfull: Yes(0) No(0)
- no. of cube required =9*10*3=270
- 9 years agoHelpfull: Yes(0) No(0)
- 270 IS THE ANS

- l=9cm
b=10cm
h=3cm
vol of cube=l*b*h
=9*10*3
=270cubic cm.
no of 1cubic cm that fullfill this vol is 270/1
=270cubic cm
