Answers:
Internal height is approximately 28.5714285714286 cm
Internal surface area is roughly 9628.57142857143 square cm
Round the values however you need to
==========================================================
Work Shown:
1 L = 1000 mL
1 L = 1000 cm^3
60 L = 60,000 cm^3 (multiply both sides by 60)
The cooler has volume of 60,000 cubic cm. Let V = 60000
Assuming the cooler is a rectangular prism (aka a block), then we can say
volume = length*width*height
V = L*W*H
60000 = 60*35*H
60000 = 2100H
2100H = 60000
H = 60000/2100
H = 28.5714285714286 which is approximate
And the surface area (SA) is
SA = 2*(LW + LH + WH)
SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)
SA = 9628.57142857143 which is also approximate
Units for the surface area are in square centimeters.
Answer:
g=8
Step-by-step explanation:
If width of rectangle is a, then length is 4a and area = 4a2<span> which is given as 100 m</span>2<span>. So a=5. Perimeter of rectangle= a+a+4a+4a = 10a= 50m</span>
Answer:
Step-by-step explanation:
Let the variable be 'x'.
- Sum of 3 and x = x + 3
- 4 times the sum of 3 and x = 4 (x + 3)
Expression : 4 (x + 3)
On expanding ,
4 (x + 3)
= (4*x) + (4*3)
= 4x + 12 ⟶ equivalent expression to the statement .
The awnser is D. It's correct.
