Surface are just means that you need to find the area of every face, then add.
TO find the Area of the rectangle do 16*8 = 128
For the triangle the area formula is b*h*1/2 So do 7*8*1/2= 28
There are four sides total and two triangles and two rectangles so 28+28+128+128= 312
SO the surface area is 312 in cubed
V of rectangular prism = l * w * h = 12 * 2 * 312 = 7,488 in³
V of one cube with side lengths 12 = l * w * h = 12 * 12 * 12 = 1,728 in³
Divide the volume of rectangular prism by the volume of the cube.
7488 / 1728 = 13 / 3 or 4.3. . .
Let the full marks be represented by = x
As given, 80% of x is 75
So,

x= 
x=93.75
Hence, full marks is 93.75
We can check also-
=75
Answer:
A
Step-by-step explanation:
Answer:
The answer is 'The slope of g(x) is less than the slope of f(x)'
Step-by-step explanation:
Given the graphs of f(x) and g(x). we have to compare the slops of these two.
The graph of f(x) passes through the points (1,0) and (2,2)
∴ 
The graph of g(x) passes through the points (0,2) and (2,3)
∴ 
As 
This shows that the
The slope of g(x) is less than the slope of f(x).
