Q. Cristian put a large rock on the bottom of the terrarium he made for his pet turtle. The rock is a right rectangular prism 10 cm 10 \mathrm{~cm} wide by 12 cm 12 \mathrm{~cm} long. The rock displaces 1800 cm3 1800 \mathrm{~cm}^{3} of water.\newlineHow high is the rock?\newlinecm
  1. Understand Problem: Understand the problem and identify the formula to use.\newlineThe volume of a right rectangular prism is given by the formula V=lwhV = lwh, where ll is the length, ww is the width, and hh is the height. We are given the volume (VV), the width (ww), and the length (ll), and we need to find the height (hh).
  2. Plug Values: Plug the known values into the volume formula and solve for the height hh. We know that V=1800cm3V = 1800 \, \text{cm}^3, w=10cmw = 10 \, \text{cm}, and l=12cml = 12 \, \text{cm}. The formula becomes 1800cm3=10cm×12cm×h1800 \, \text{cm}^3 = 10 \, \text{cm} \times 12 \, \text{cm} \times h.
  3. Calculate Height: Calculate the height hh by dividing the volume VV by the product of the width ww and the length ll.h=Vl×w=1800cm310cm×12cm=1800cm3120cm2=15cm.h = \frac{V}{l \times w} = \frac{1800 \, \text{cm}^3}{10 \, \text{cm} \times 12 \, \text{cm}} = \frac{1800 \, \text{cm}^3}{120 \, \text{cm}^2} = 15 \, \text{cm}.
  4. Verify Calculation: Verify the calculation to ensure there are no math errors.\newlineRe-calculate the height using the formula: h=1800cm3(10cm×12cm)=1800cm3120cm2=15cmh = \frac{1800 \, \text{cm}^3}{(10 \, \text{cm} \times 12 \, \text{cm})} = \frac{1800 \, \text{cm}^3}{120 \, \text{cm}^2} = 15 \, \text{cm}. The calculation is correct.
