Answer: 81 ft^2
Hello! The surface area of the rectangular prism will follow this process:
Right triangle area: (1/2)bh
So that 6ft (4.5ft) = 27ft^2/2; though when one multiplies that by 2 (as there are two right triangles), we get a surface area of 27ft^2.
For the rectangle's area, it's slightly more deviated since each face is different in length: bh
Face 1 = 3ft(7.5ft) = 22.5ft^2
Face 2 = 3ft(6ft) = 18ft^2
Face 3 = 4.5ft(3ft) = 13.5 ft^2
Thus, if we add these all together (27ft^2. + 22.5ft^2 + 18ft^2 + 13.5 ft^2), we get 81 ft^2
Answer:
72 possible combinations
Step-by-step explanation:
In order to calculate the total number of possible outcomes of using one of each category we simply need to multiply the total number of books from each category together. Since there are 4 mysteries, 3 adventures, and 6 science fiction books we multiply these values with one another.
4 * 3 * 6 = 72
Finally, we can see that there are a total of 72 possible combinations for displaying one book from each category together.
