Answer:
Juan will have 3 digits after decimal.
Step-by-step explanation:
A number having one digit after decimal when multiplied by another number having single digit after decimal, we get a number having two digits after decimal.
Example:
0.2 × 0.6 = 0.12
0.3 × 0.3 = 0.09
Now we have to find the volume of a box having dimensions 7.2 units by 8.4 units by 12.8 units.
Volume = 7.2×8.4×12.8 [Each number having one digit after decimal]
= 774.144 unit³ [Number with 3 digits after decimal]
Therefore, Juan will have 3 digits after decimal in the final answer.
