42.5 cm³of material to make the second prism.## Amount of material available

V= 900 cm³ – 14.5 cm³= 885.5 cm³## Scale factor

(scale factor)³= volume of second prism/volue of first prism## Volume of second prism

volume of second prism, V’ = (scale factor)³ × volume of first prism= 4³ × 14.5 cm³ = 928 cm³## Amount of material more needed

V”‘ = V’ – V= 928 cm³ – 885.5 cm³= 42.5 cm³42.5 cm³of material to make the second prism.amountofmaterialhere:Answer:42.5 cm³ for K12
