Answer:
The lateral surface area of a prism is the sum of the surface areas of the sides of the prism.
Since the bases of the prism are triangles, there are three sides. The area of each lateral is the product of a side of the triangle times the height of the prism.
We can express this as Lateral Surface Area LSA = (s1xh) + (s2xh) + (s3+h), where "s1, s2, s3" are the lengths of the sides of the triangle and "h" is the height of the prism.
We can factor out "h" to get LSA = hx(s1+s2+s3) where the factor "s1+s2+s3" is the perimeter of the triangle.
Solving for "h", we get h = LSA / (s1+s2+s3)
For your specific problem, h = 300 / (4 + 5 + 6) = 300 / 15 = 20
Answer:
A is correct
Step-by-step explanation:
Quantity of paint left = 
gallons
Solution:
Quantity of yellow paint = 
gallons
Quantity of green paint = 
gallons
Quantity of blue paint = 
gallons
Quantity of paint used = 
gallons of each paint
Quantity of paint left = 
gallons of each paint
Quantity of paint left = 
Taking LCM for 5, 6, 8, we get LCM = 120
Hence, Mark will have gallons of paint left after painting the mural.
