Raul is building a house. On day 1, he uses 3 bags of cement. On each of the following 3 days, he uses 3 times the number of bags used the previous day. How many bags of cement does he use in the last 3 days?

Sagot :

Answer:

117 bags

Step-by-step explanation:

Day 1: 3 bags

Day 2: 3 × 3 = 9 bags

Day 3: 9 × 3 = 27 bags

Day 4: 27 × 3 = 81 bags

Total: 9 + 27 + 81 = 117 bags

Answer:

81 bags of cement in the last 3 days.

Step-by-step explanation:

On the first day he used 3 bags.

The second day he used twice that amount so that would be 3²=9

The third day he used twice the amount he used the second day. So that would be 9²=81.

He used 81 bags of cement in the last 3 days.

Hope this helps!

If not, I am sorry.
