Answer:
2 B + p h
Step-by-step explanation:
The Surface Area = 2 B + p h
B is the area of the triangular base of prism
p perimeter of the base and
h the height of the prism
Answer:
Step-by-step explanation:
Let us assume that both prisms are similar, so we can use proportions to solve for the volume of prism made by triangle XYZ.
Let us find the proportion between the sides of both triangles.



Since for volume of triangular prism we multiply base area and height of the prism, this means we will have to multiply the proportion of each side length 3 times to find the proportion of volumes between our both prism.
So we can set proportion for volume of both prisms as:

Upon substituting volume of prism made by triangle PQR we will get,
Let us multiply both sides of our equation by 7776 cubic inches.


Therefore, the volume of prism made by triangle XYZ is 2304 cubic inches.
Answer:
D
Step-by-step explanation:
first find the perimeter of both triangles
Original perimeter: 72 in
scaled perimeter: 24 in
A is wrong since the scaled perimeter is actually smaller.
B is wrong because its not 6 times smaller
C is wrong since it's not 1/9 of the original
D is correct since the scaled is a 1/3 of the original perimeter (72*1/3 = 24)
Answer: $0.6
Step-by-step explanation:
15cookies= $9
1 cookie = x
Cross multiply
15x= 9
Divide both sides by 15
x= 9/15= 3/5= $0.6
