Units: cubic yard to cubic metre
Tutoring science, unit conversions are important. The tutor mentions a common one.
Between a yard and a metre, there seems little difference: a yard is 91.44% of a metre. Yet, a cubic yard, being 0.9144×0.9144×0.9144, is only 76.5% of a cubic metre: it’s a difference that’s harder to ignore.
