Answer:
(c)
Explanation:
for the volume of a box all three dimensions must be multiplied with each other to create a cubic result.
3x²y × 4y²z × 5z²x
we need to combine the elements belonging to each other = that can be combined for simplification :
the constants, the x, the y and the z.
3×4×5 = 60
x²×x = x³
y×y² = y³
z×z² = z³
so, in total, that multiplication result is
60x³y³z³
therefore, (c) is the right answer
