Answer: 1,029.819 cm³
Step-by-step explanation: In this problem, we're asked to find the volume of a brick. To find the volume of a brick, we use the formula for the volume of a rectangular prism.
To find the volume of a rectangular prism or a prism whose base is a rectangle, we use the following formula.
Volume = length × width × height
Since the brick has a length of 20.3 centimeters, a width of 8.9 centimeters, and a height of 5.7 centimeters, we can plug this information into the formula.
Volume = (20.3 cm) (8.9 cm) (5.7 cm)
Volume = 1,029.819
Therefore, the volume of the brick is 1,029.819 cm³.
Also, it's important to understand that we can plug any number in for the length width or height as long as it's one of the numbers given and it's not used more than once.
This is because the commutative property of multiplication tells us that changing the order of the factors doesn't change the product.
