Q3 Subjective Medium
In the United States, a doll house has the scale of $1:12$ of a real house (that is,each length of the doll house is $\dfrac{1}{12}$ that of the real house) and a miniature house (a doll house to fit within a doll house) has the scale of $1:44$ of a real house. Suppose a real house has a front length of $20\ m$, a depth of $12\ m$, a height of $6.0\ m$, and a standard sloped roof (vertical triangular faces on the ends) of height $3.0\ m$ In cubic meters, what are the volumes of the corresponding
miniature house?
