It would be 250 cu. ft.
Say the larger box measures 10x10x20 which would give you a volume of 2,000 cu. ft. The smaller box then would measure half of those lengths or 5x5x10 which would be 250 cu. ft.
So it's like 'which one of the number given is a factor of, say, 10' and the choices are 4,5,7,9. the answer is 5 so just factor out the equation
the factored out form is
factor out the 3x^2 and get
(3x^2)(3x^2-2x+1)
and 3x^2-2x+1 is the fourth choice
Answer:
5, 10, 20, 40, 80, 160
Step-by-step explanation:
5-10 is double 5. 10-20 is double 10 meaning you double each time
Double 20 is 40
Double 40 is 80
Double 80 is 160
2520
= 10 * 252
= 2 * 5 * 2 * 126
= 2 * 5 * 2 * 2 * 63
= 2 * 5 * 2 * 2 * 7 * 3 * 3
= 2^3 * 3^2 * 5 * 7
