Answer: 284 cubes.
Step-by-step explanation:
By definition, the volume of a rectangular prism can be calculated by multiplying its dimensions.
Knowing that the dimensions of this box are 
, we get that the volume of the box is:
The formula for calculate the volume of a cube is:
Where "s" is the lenght of a side.
Kwnowing that the a cube has a side of 1.5 cm, we get that the volume of one cube is:
Dividing 
by 
we get the greatest number of cubes that can fit in the box:

Answer:
10 easy levels and 10 difficult levels
Step-by-step explanation:
Given data
let the number of easy levels be x
and the number of difficult levels be y
so
x+y= 20----------1
and
3x+5y= 80------2
from 1
x=20-y
put this in 2
3(20-y)+5y= 80
60-3y+5y=80
2y=80-60
2y=20
y= 20/2
y= 10
put y= 10 in 1
x+10=20
x=20-10
x= 10
Hence Kiran played 10 easy levels and 10 difficult levels
For me personally i can work nearly any equation with a calculator. definitely a good choice <span />
