Answers

  1. The volume of her gold ring in cubic centimeters will be 12.6 cubic centimeters.

    What is the volume of the rectangular prism?

    Let the prism with a length of L, a width of W, and a height of H.
    a prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases.
    Then the volume of the prism is given as
    V = L x W x H
    She gets a rectangular glass with a base of 7 cm by 4.5 cm and fills the glass 8.8 cm high with water.
    Laura drops her gold ring into the glass and measures the new height of the water to be 9.2 cm.
    Then the volume of her gold ring in cubic centimeters will be
    V = 7 × 4.5 ×(9.2 – 8.8)
    V = 7 × 4.5 × 0.4
    V = 12.6 cubic centimeters
    The volume of her gold ring in cubic centimeters will be 12.6 cubic centimeters.
