What is the volume of this container?

1,875cm^3 (I believe this is the answer, It's been a while since I've done this so feel free to correct me.)

Step-by-step explanation:

(20 x 5 x 20) - (5 x 5 x 5) =

20x5x20= 2,000

5x5x5= 125

2,000-125= 1,875

35 is an outlier

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
