Therefore:

there are 6 faces multiply 25 by 6
25*6=150cm^2
Answer:
(6 × 3) divided by 8 and 3/8 × 6
Step-by-step explanation:
if you solve 6 × 3/8 you should get 18/8 which then simplifies to 9/4. if you go though each answer choice solving each problem you should get 9/4 and if you dont then that is not the answer. the first 2 answer choices equal 16 which is not 9/4 and the 4th answer choice will give you 4 and 6 × 8/3 gives you 48/3 which gives you 16 so only the 3rd and last answer choices are correct
The answer is 1200
3/5=x/2,000
2,000/5=400
3 x 400=1200
