Answer:
[tex]A=15\ cm^2[/tex]
Step-by-step explanation:
Given that,
The height of the cuboid = 6 cm
The volume of the cuboid = 90 cm²
We need to find the area of the shaded face.
The volume of a cuboid is given by the formula as follows :
[tex]V=A\times h[/tex]
A is area of the shaded face
Putting all the values,
[tex]A=\dfrac{V}{h}\\\\A=\dfrac{90}{6}\\\\A=15\ cm^2[/tex]
So, the area of the shaded face is [tex]15\ cm^2[/tex].
