I believe the answer is 12, with 9 remaining students.
If you need g/mL then just divide
0.3065g/138.03mL=0.002 g/mL
Because a rectangle has four sides and the opposite sides are the same length, you can simply multiply each of the given sides (5 5/8 feet and 6 1/4 feet) by 2, and then add them together.
5 5/8 × 2 = 11 1/4.
6 1/4 × 2 = 12 1/2
11 1/4 + 12 1/2 = 23 3/4 or 23.75
Therefore, the perimeter of the rectangle is 23.75 feet.
The surface area of a sphere is given by the formula
.. A = 4π*r^2
.. A = 4π*(1.25 in)^2 ≈ 20 in^2
