Which expression is equivalent to 7/12 (Fractions) 1. 12 x 7

2. 7 x 12

3. 7 divided by 12

4. 12 divided by 7

Volume is length times width times height so
20 times 8 times 30 which is 4,800
surface area is ph (p is perimeter of base), h is height.
so perimeter would be length+length+width+width so 20+20+8+8 which is 56. so multiply 56 times 30 which is 1680. hope this !
