In a robotics competition, a robot must be built with a specific
maximum starting height, width, and depth. In order to meet the
height requirements, a robot must fit in the judge’s plexi-glass box.
The box is a rectangular prism that has a surface area of 1 728 in^2, a
width of 15 inches, and a length of 18 inches. The Mad Hatter robot
is 17.75 inches tall in its starting position. Does the Mad Hatter
meet the height requirement?
My answer: yes, but I don't know how to find the height of the plexiglass box? The formula I have been taught is SA = 2lw + 2hw + 2lh. Please help
the box's height h can be found using
2(18*15 + 15h+18h) = 1728
h = 18
Looks good to me.
