Perimeter=L+W×2=Meter Area=L×W=Meter square Surface Area=L×W×6(if its a cube)=Meter Square Volume=L×W×H=Meter Cube 8*8=64*3 =192 I apologize if am wrong Good Luck!
The area of a triangle is 1/2bh (one half, base times height) which is the same as half of 7x8. To find the surface area, do the area four times. The answer is 112
