Step-by-step explanation:
The dimensions of the cuboid are 5 cm, 7 cm and 9 cm.
The formula for the surface area of the cuboid is as follows :

We have,
b = 9 cm, l = 7 cm and h = 5 cm
So,

Jamie forgets to multiply 143 by 2 as the formula for surface area contains 2 as well.
They are both similar because you just have to multiply 7 x 2 and then add the zeros. 7 x 20 is 140 and 7 x2000 is 14000
Answer : The cost of 10 balls will be, 13.5 dollars
Step-by-step explanation :
As we are given the following expression:

where,
P = total price (in dollars)
n = number of balls used
Given:
n = number of balls used = 10
Now we have to determine the cost of 10 balls.




Thus, the cost of 10 balls will be, 13.5 dollars
