Answer:
Step-by-step explanation:
This problem is on the mensuration of solid shapes, a box/cube.
Given data
[tex]Length l = 3in\\\\Width w= \frac{1}{12}in \\\\Height h = 4in[/tex]
we know that the expression for the volume of a cube is
[tex]volume= l*w*h\\\\substituting \\\\volume= 3* \frac{1}{12}* 4\\ volume= \frac{12}{12} = 1 in^{3}[/tex]
