Question 99965
write and expression for width in terms of L
Given: width is 4 less than the length
width = L - 4


write an expression for height in terms of L
Given: height is 3 more than twice the width
since width is equal to L-4
height = 3 + 2(L - 4)


find the volume of the box if L = 10
Known: Volume equals length times width times height
{{{V=(L)(W)(H)}}}
{{{V=(L)(L-4)(3+2(L-4))}}}
{{{V=(10)(10-4)(3+2(10-4))}}}
{{{V=(10)(6)(3+2(6))}}}
{{{V=(10)(6)(3+12)}}}
{{{V=(10)(6)(15)}}}
{{{V=(60)(15)}}}
{{{V=900}}}
