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

In the remaining part of the semester, Zachery wrote an average of 10,000 words per month to complete his final project for the course.
We are given that Zachery has to write a total of 95,234 words.
Total words to be written = 95,234 words.
Words already written in the first month = 35,295 words.
Words already written in the second month = 19,240 words.
Words written in total = 35,295 words + 19,240 words.
= 54,535 words
Words left for writing = 95,234 words - 54,535 words
= 39,699 words
months left = 4
Average Words written in remaining month = 39,699 words / 4
= 9924.75 words.
= 10,000 words.
Therefore, in the remaining part of the semester, Zachery wrote an average of 10,000 words per month to complete his final project for the course.
