Q. Whitney is making a strawberry cake for her brother's birthday. The cake pan is a right rectangular prism 20cm20\,\text{cm} wide by 28cm28\,\text{cm} long. Whitney puts 1848cm31848\,\text{cm}^{3} of batter into the pan. \newlineHow deep is the cake batter?\newlinecm\square\,\text{cm}
  1. Calculate Volume of Cake Pan: Calculate the volume of the cake pan using the formula for the volume of a rectangular prism: Volume=length×width×height\text{Volume} = \text{length} \times \text{width} \times \text{height}.
  2. Plug in Given Dimensions: Plug in the given dimensions: Volume = 28cm×20cm×height.28\,\text{cm} \times 20\,\text{cm} \times \text{height}.
  3. Set Equal to Solve for Height: We know the volume of batter Whitney put into the pan is 1848cm31848\,\text{cm}^3. Set this equal to the volume of the pan to solve for the height (depth): 28cm×20cm×height=1848cm328\,\text{cm} \times 20\,\text{cm} \times \text{height} = 1848\,\text{cm}^3.
  4. Isolate Height: Divide both sides of the equation by the product of the length and width to isolate the height: height=1848cm3(28cm×20cm)\text{height} = \frac{1848\,\text{cm}^3}{(28\,\text{cm} \times 20\,\text{cm})}.
  5. Calculate Height: Calculate the height: height=1848cm3560cm2\text{height} = \frac{1848\text{cm}^3}{560\text{cm}^2}.
  6. Perform Division: Perform the division: height=3.3cm.\text{height} = 3.3\,\text{cm}.
