Answer: C : the total volume is 117
Explanation:
we need to find the volume of each object and then add them together at the end
ill call the smaller object #1 and the bigger object #2
#1:
volume = length * width * height
v = Lwh
v = 4 * 3 * 1 = 12
the volume of the first object is 12
(remember the unit of volume is always cubed)
#2:
v = Lwh
v = 7 * 5 * 3 = 105
the volume of the second object is 105
now let's add them together to find the combined volume!
object 1 + object 2 = total combined volume
12 + 105 = 117
the total volume is 117
(or option C)
