Answer:
The volume of the box is 56 cm ^3
The surface area or the amount of cardboard used is 100 cm ^3
Step-by-step explanation:
for the volume you multiply the top the side and the bottom of the box together 7*4*2=56 ^3
For the amount of cardboard used we have to find the area of all the sides then add them together. 7*4=28 28*2=56. we multiply it by 2 because there is 2 sides with the same measurements for each side.
2*4=8 8*2=16
2*7=14 14*2=28
56+28+16=100
Hope this helps!
