It is true sometimes because it only has one solution.
1331= lwh or 1331= x^3
So take cube root of both sides and you will get 11.
Since the formula for area is length times width, the answer is 11x11 which equals 121.
So the square area of the base is 121mm^2
Company B because if u multiply 20×3 then you would only have to pay $60 and if u buy it from company A you would have to multiply 11×3 and then multiply 33× 20 and then you would have to pay $660 so u would save more with company B
