32 2/3
(32.6 repeating)
Step-by-step explanation:
29/3 is 9 (just make it not 3 Xs,) so x=9

41 2/3 - 9 = 32 2/3
In general, to find the surface area of a prism (a shape with 2 bases) is
Area of Base*2 + Lateral Area (Lateral area = Perimeter of bases * height)
#9 Area of base= 2×1÷2=1 *2=2
Lateral area= 2+1+2.2=5.2 5.2*3=15.6
Answer=17.6
#10 Area of Base= 120*2=240
Lateral Area=500
Answer=740
#11
Area of base=8*2=16
Lateral Area= 41.4
Answer=57.4
Answer:
