Answer:
94 cm^2
Step-by-step explanation:
The surface area of a rectangular prism can be found using:
A=2(wl+hl+hw)
We know the width is 3, the height is 5, and the length is 4. We can substitute 3 in for w, 5 in for h, and 4 in for l.
A=2((3*4)+(5*4)+(5*3))
Multiply 3 and 4
A=2(12+(5*4)+(5*3))
Multiply 5 and 4
A=2(12+20+(5*3))
Multiply 5 and 3
A=2(12+20+15)
Add 12 and 20 and 15
A=2(47)
Multiply 2 and 47
A=94
So, the the surface area is 94 cm^2
Answer:
The total surface area of this cuboid is 132.5 sq.cm
Answer:
160 cm^2
Step-by-step explanation:
The shaded area is the triangle with a base of 20 and a height of 16, I take it.
Area = 1/2 b* h
Area = 1/2 * 20 * 16
Area = 160 cm^2
Answer:
100 customers
Step-by-step explanation:
The computation of the number of dell customers would be in the spring is shown below:
Given that
In winter season
The ratio of daily customers to weekly customers = 1:5.
In Spring season :
The ratio of daily customers to weekly customers = 4:2.
And, the Number of the weekly customer in the winter is 125
So if we can see that the weekly customers would be 5 times of daily customers
So, the daily customers in winter is
= 125 ÷ 5
= 25 customers
Now in the spring it would be
= 25 × 4
= 100 customers
the answer is B. 7•3 is 27
