Find the number of cubic feet in a rectangular solid that is \( 5.3 \mathrm{ft} \). by 6.8 ft. by 2.9 ft . Find the answer to the nearest tenth.

To find the volume of a rectangular solid, you multiply its length, width, and height. Here, the dimensions are \(5.3 \, \text{ft}\), \(6.8 \, \text{ft}\), and \(2.9 \, \text{ft}\). So, the calculation is: \[ \text{Volume} = 5.3 \times 6.8 \times 2.9 \] Calculating that gives: \[ \text{Volume} = 5.3 \times 6.8 = 36.04 \] \[ \text{Volume} = 36.04 \times 2.9 = 104.576 \] Rounding to the nearest tenth, the volume of the rectangular solid is approximately \(104.6 \, \text{ft}^3\).
