Answer:
the answer is 40 boys
Step-by-step explanation:
Let's say there are x boys who play both cards and carrom.
We setup up an equation that involved all information given and x.
Boys who only play cards = 45-x
Boys who only play carrom = 20-x
Boys who play both = x
Add there together and you should get 60, which is the total number of students in the class.
(45-x)+(20-x)+x=60
65-x=60
x=5
Boys who only play cards=45-x=45–5=40
hope it helps you

Answer:
Surface area = 144 mi.²
Step-by-step explanation:
Surface area of the triangular prism = bh + (P)L
Where,
b = base of triangular base = 6 mi.
h = height of triangular base = 8 mi.
P = Perimeter of triangular base = 10 + 8 + 6 = 24 mi.
L = height of the prism = 4 mi.
Plug the values into the formula
Surface area = 6*8 + (24)4
= 48 + 96
= 144 mi.²
