A composite figure is made up of a rectangular prism sandwiched between two halves of a cylinder. Which of the following surface area equations could you use to find the total surface area of the solid? Select all that apply.

a. SA = 2l L + l^2
b. SA = 2 pi rh + 2 pi r^2
c. SA = 2B + Ph
d. SA = 2lw + 2lh + 2wh
e. SA = 4 pi r^2
f. SA = pi r L + pi r^2
