Full solution

Q. A cube of gold with an edge length of 33 inches (in) is melted and reformed into a rectangular prism with a width of 22.55 in and a height of 2in 2 \mathrm{in} . If the volume is unchanged during melting, what is the length of the prism of gold in inches?
  1. Calculate volume of original gold cube: Calculate the volume of the original gold cube using the formula for the volume of a cube, V=s3V = s^3, where ss is the side length of the cube.\newlineGiven side length (ss) = 33 inches.\newlineV=33=27V = 3^3 = 27 cubic inches.
  2. Determine volume of rectangular prism: Determine the volume of the rectangular prism using the formula for the volume of a rectangular prism, V=lwhV = lwh, where ll is the length, ww is the width, and hh is the height.\newlineSince the volume is unchanged during melting, the volume of the rectangular prism is also 2727 cubic inches.\newlineGiven width (ww) = 2.52.5 inches and height (hh) = 22 inches.
  3. Solve for length of rectangular prism: Solve for the length ll of the rectangular prism using the volume equation, V=lwhV = lwh.27=l×2.5×227 = l \times 2.5 \times 2l=272.5×2l = \frac{27}{2.5 \times 2}
  4. Calculate length of rectangular prism: Calculate the length ll of the rectangular prism.l=275l = \frac{27}{5}l=5.4 inches.l = 5.4 \text{ inches}.
