Answer:
Hey No worries. Its very easy.
Step-by-step explanation:
Look,
Volume= 84 in.cube
Length=6 in.
Breadth=2 in.
therefore, Height= Volume/(Length*Breadth)
=84/(6*2)
=84/12
=7
h = 7 in
The volume (V) of a cuboid is calculated using the formula
V = lbh ( l is length, b is breadth and h is height )
Given V = 84 in³, then
lbh = 84 ← substitute l = 6 and b = 2
6 × 2 × h = 84
12h = 84 ( divide both sides by 12 )
h = 7
substitute the place of the X
