Answer:400
Step-by-step explanation: the formula for the volume of a rectangular prism is length times width times height
(-X-13)+(X+13)+(X-13)
The positive x and negative x cancel out and equal zero. The positive 13 and negative 13 cancel and equal zero also. Then you are left with (x-13)
The simplest form of this sum is 670.
Answer:
C im pretty sure
Step-by-step explanation:
Because the square taken out has a 4x4 area which is 16 and the area of the whole square used to be 14x14 which is 196 and if u subtract 16 from that you get 180
If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5
