Maria built a sand castle that is made of two rectangular prisms. She used one bag of sand. If there are 2,000 cubic inches of sand in a bag of sand, how much sand was left after Maria built her sand castle? \( 5 . G R .3 .3 \)

To determine how much sand was left after Maria built her sand castle, we need to follow these steps: 1. **Identify the total amount of sand in the bag.** - Maria has 1 bag of sand, which contains \( 2000 \) cubic inches. 2. **Calculate the volume of the sand castle.** - Since the problem states that the sand castle is made of two rectangular prisms, we need to know the dimensions of these prisms to calculate their total volume. However, the problem does not provide these dimensions. 3. **Assuming we had the dimensions, we would calculate the volume of each rectangular prism using the formula:** \[ V = l \times w \times h \] where \( l \) is the length, \( w \) is the width, and \( h \) is the height of the prism. 4. **Add the volumes of the two prisms to find the total volume of the sand castle:** \[ V_{total} = V_1 + V_2 \] 5. **Subtract the total volume of the sand castle from the total amount of sand in the bag to find the amount of sand left:** \[ \text{Sand left} = 2000 - V_{total} \] Since we do not have the dimensions of the rectangular prisms, we cannot calculate the exact volume of the sand castle. If you can provide the dimensions of the two rectangular prisms, I can help you calculate the volume and determine how much sand was left.
