Answer:

G, 7 cm

Step-by-step explanation:

the volume of a box is V = lwh

in this problem, we know the volume, length, and width and we are asked to find the height. lets plug in the known values into the formula

378 = (6)(9)h <multiply 6 and 9 together

378 = 54h

now we want to divide both sides by 54 to get h alone, and we will have our answer for the height

378/ 54 = 7

54h/54 = h

h = 7

our height for this box is 7 cm, we can plug this into the original equation to check, but it is not necessary
