Q. Whitney is making a strawberry cake for her brother's birthday. The cake pan is a right rectangular prism 20 cm 20 \mathrm{~cm} wide by 28 cm 28 \mathrm{~cm} long. Whitney puts 1848 cm3 1848 \mathrm{~cm}^{3} of batter into the pan.\newlineHow deep is the cake batter?\newlinecm
  1. Identify Volume and Dimensions: Identify the volume of the cake batter and the dimensions of the cake pan.\newlineThe volume of the batter is given as 1848cm31848 \, \text{cm}^3.\newlineThe dimensions of the cake pan are 20cm20 \, \text{cm} in width and 28cm28 \, \text{cm} in length.\newlineWe need to find the depth (height) of the batter in the pan.
  2. Use Volume Formula: Use the formula for the volume of a right rectangular prism.\newlineThe volume VV of a right rectangular prism is given by the formula V=length×width×heightV = \text{length} \times \text{width} \times \text{height}.\newlineHere, we know the volume (V=1848cm3V = 1848 \, \text{cm}^3), the length (28cm28 \, \text{cm}), and the width (20cm20 \, \text{cm}). We need to find the height (hh).
  3. Rearrange Formula for Height: Rearrange the formula to solve for the height.\newlineThe formula for the volume of the prism is V=length×width×heightV = \text{length} \times \text{width} \times \text{height}, which can be rearranged to solve for height (h)(h) as follows:\newlineh=V(length×width)h = \frac{V}{(\text{length} \times \text{width})}
  4. Calculate Height: Plug in the known values and calculate the height.\newlineh=1848cm328cm×20cmh = \frac{1848 \, \text{cm}^3}{28 \, \text{cm} \times 20 \, \text{cm}}\newlineh=1848cm3560cm2h = \frac{1848 \, \text{cm}^3}{560 \, \text{cm}^2}\newlineh=3.3cmh = 3.3 \, \text{cm}
  5. Check Calculation: Check the calculation for any mathematical errors.\newlineRechecking the calculation:\newlineh=1848cm3560cm2h = \frac{1848 \, \text{cm}^3}{560 \, \text{cm}^2}\newlineh=3.3cmh = 3.3 \, \text{cm}\newlineThe calculation seems correct, and there are no mathematical errors.
