In the supply closet, they found 12 boxes of pencils with 12 pencils in each box. The 54 students also brought 10 pencils each. How many pencils did they have for the mission box? Circle your final answer.

To find the total number of pencils available for the mission box, we need to calculate the pencils from the boxes and the pencils brought by the students. 1. **Calculate the total number of pencils in the boxes:** - There are 12 boxes, and each box contains 12 pencils. - Total pencils from boxes = Number of boxes × Pencils per box \[ \text{Total pencils from boxes} = 12 \times 12 \] 2. **Calculate the total number of pencils brought by the students:** - There are 54 students, and each student brought 10 pencils. - Total pencils from students = Number of students × Pencils per student \[ \text{Total pencils from students} = 54 \times 10 \] 3. **Add the total pencils from boxes and students to find the total pencils for the mission box:** \[ \text{Total pencils for mission box} = \text{Total pencils from boxes} + \text{Total pencils from students} \] Now, let's perform the calculations step by step. ### Step 1: Calculate total pencils from boxes \[ \text{Total pencils from boxes} = 12 \times 12 = 144 \] ### Step 2: Calculate total pencils from students \[ \text{Total pencils from students} = 54 \times 10 = 540 \] ### Step 3: Calculate total pencils for the mission box \[ \text{Total pencils for mission box} = 144 + 540 = 684 \] Thus, the total number of pencils for the mission box is **684**. **Final Answer: 684**
