Find the surface area of the following prism.
6 1/2 cm
4 cm
4 1/5 cm
9 cm
5 1/4 cm

226 11/20 cm^2.

Step-by-step explanation:

This consists of 2 trapezoids and 4 rectangles.

Area of the 2 trapezoids = 2 * 4 *(6 1/2 + 5 1/4 ) /2

= 47 cm^2.

Area of the 4 rectangles =  4*9 + 6 1/2 * 9 +  4 1/5 * 9 + 9* 5 1/4

=  36 +  117/2 + 189/5 + 189/4

= 3591/20 cm^2

Total surface area = 47 + 3591/20

= 4531/20

= 226 11/20 cm^2.

the discriminant is 64 + 4*1*12 = 112

this is prime.
