Calculate the volume of both the prism and the cubes:
Prism:
Volume = 20 x 2 x 3.25 = 130 cubic inches.
Volume of cube:
Volume = S^3 = 1/4^3 = 1/64 ( 0.015625)
Divide the area of the prism by the area of the cube:
130 / 1/64 = 130 * 64 = 8,320
It would take 8,320 cubes to fill the prism.
The least whole number with 5 digits is greater. The greatest number with 4 digits is 9999, and the least whole number with 5 digits is 10000. 9999 < 10000.
Answer:
Step-by-step explanation:
I'm not sure my way is going to be any quicker or better. Let's take an example.
Suppose you start with 456
Put a decimal at the end of the 6. You get 456.
Shift the decimal to the left one place 45.6
Divide by 2
22.8 (done mentally)
Note: dividing by 2 is easier than dividing by 5. Or multiplying by 5 for that matter.
Check the result.
456 * 5/100 =2280 / 100.
Shift a decimal 2 places to the left.
22.80 which agrees with your result.
