To determine the amount of sand Lokota needs for the sandbox, we will use the formula for the area of a rectangle, typically given as \( A = b \times h \), but you mentioned a formula \( A = 12bh \), which might indicate that there is a scaling factor involved.
Here are the steps to complete the statements:
-
Write the formula: \( A = 12bh \).
-
Substitute the known values for \( b \) and \( h \): \[ A = 12(2.4)(3.5) \]
-
Now, simplify the equation: \[ A = 12 \times 2.4 \times 3.5 \]
- First, calculate \( 12 \times 2.4 = 28.8 \).
- Then, multiply \( 28.8 \times 3.5 = 100.8 \).
So, the area of the sandbox is: \[ A = 100.8 , m^2 \]
Thus, the complete statement would look like this:
- First, write the formula: \( A = 12bh \).
- Next, use parentheses when you substitute \( 2.4 \) for \( b \) and \( 3.5 \) for \( h \).
- Now, simplify by \( 12, 2.4, \) and \( 3.5 \).
- The area of the sandbox is \( 100.8 , m^2 \).
