Answer

$731.52 \text { cm}$

Work Step by Step

First, convert the given measurement to inches by multiplying $\dfrac{36 \text{ in.}}{1 \text{ yd}}$ to obtain: $\require{cancel}=8 \cancel{\text{ yd}}\cdot \dfrac{36 \text{ in}}{1 \cancel{\text{ yd}}} \\=8(36) \text{ in} \\=288 \text { in.}$ Then, convert inches to cm by multiplying $\dfrac{2.54 \text{ cm}}{1 \text{ in.}}$ to obtain: $\require{cancel}=288 \cancel{\text{ in.}}\cdot \dfrac{2.54 \text{ cm}}{1 \cancel{\text{ in.}}} \\=288(2.54) \text{ cm} \\=731.52 \text { cm}$
