Question

Quizplus · Accepted Answer

The surface area of a rectangular solid is given by the formula $2lw + 2lh + 2wh$, where $l$ is the length, $w$ is the width, and $h$ is the height. Given $l = 6m$, $h = 3m$, and the total surface area is $108m^2$, we can set up the equation $2(6w) + 2(6*3) + 2(3w) = 108$. Simplifying, we get $12w + 36 + 6w = 108$, which further simplifies to $18w = 72$, leading to $w = 4m$.
