1. What is the surface area of this rectangular prism? A. 16 square units
B. 32 square units
C. 48 square units
D. 64 square units

I believe it is 64 ( I might be wrong)

Step-by-step explanation:

ok so in the picture, the top of the rectangle has 8 square units so that means that the base also has 8 square units and if you look at the sides they also have 8 square unit so:

8 x 4 = 32

and then in the picture, the face of the rectangle has 16 square units so the other face also has 16 square units so:

16 x 2 = 32 plus the 32 from the sides in 64

hope that helps : )

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
