Answer:
9.504×10⁹ ft³
Step-by-step explanation:
We are told the amount of water in cubic feet per second. We need it in cubic feet per hour, then multiply that amount by 24 to get the cubic feet of water that falls in a 24-hr period. Converting the seconds to hours:
The seconds label cancels out leaving us with a label in cubic feet per hour. That number, NOT in scientific notation (we'll do that at the end) is:
396000000 cubic feet per hour.
Multiply that by 24 and you get:
9504000000 cubic feet or
9.504×10⁹ cubic feet
Alright so to find the area of a rectangular prism (a book is a rectangular prism) you need to multiply the 3 numbers they give you so you multiply 7, 812, and 2/12. after you multiply all of the numbers you add ^3 to the end because you found the volume, its not a flat shape or a 2D shape.

Step-by-step explanation:
Answer: 120, 60, 180
Step-by-step explanation:
1) Area of a rectangle's formula is:
l × w
So, looking at the diagram, we get:
6 × 20 = 120 cm²
2) Area of a trapezoid's formula is:
× h (where both a and b are the different base lengths)
So, looking at the diagram, we get:
× 4 = 60 cm²
3) Add both to find the area of the entire figure.
120 + 60 = 180 cm²
