Some key roles are to have the two fractions. In addition you need to have a common denominator and also in subtraction and in substation you may need to bring over whole numbers to make it possible.

You need to split the shape into simpler shapes so you would get a rectangular prism and a triangular prism finding the volume is pretty straightforward the formula is

Volume of a triangular prism = area of base triangle × height

The formula for finding the volume of a rectangular prism is the following: Volume = Length * Height * Width, or V = L * H * W.
After solving for this you would just have to add the 2 shapes volume together tie get the volume of the composite figure
Finding the surface area is also pretty simple since it would only require you to know the formulas

S = 2(lw + lh + wh) to find the surface area of a rectangle or prism

A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
And by adding the two surface areas of the shapes you can get the surface area of the composite figure but remember to subtract the top face of the rectangular prism and the bottom face of the triangular prism
Hope this helps <3

Alright assuming they mean total surface area since they didn't say lateral the equation to follow would be S= Ph + 2B

Start with P:
P stands for perimeter, so add up all the edges on one face of the cube.


17 + 17 + 17 + 17 = 68
Then your equation becomes
S= 68×h + 2B
h=height and that's obviously 17
so, S= 68×17 +2B

Now to find B. This is pretty easy. All you need to do is take 17×17 because you're finding the area of the base. This equals 289.

Finally this leaves us with the equation
S= 68×17+2×289

From there on you just solve it out.
This would leave you with 1734.

OLga [1]

Answer: b. histogram

Step-by-step explanation:

A histogram is a graphical summary of data previously summarized in a frequency distribution. It is an accurate representation of the distribution of numerical data, the height of each bar shows how many fall into each range(the frequency of each range). Data from a frequency distribution table can be easily summarised graphically on a histogram.

An example of histogram is shown in the attachment
