Blackboards are different sizes. You need to measure the particular blackboard with a ruler or tape measure to get the width. The width is the shorter side (the length is the longer side).
No, a ruler is used only to measure length, width or height. You must use a protractor in order to measure the degrees in an angle.
A ruler or tape measure would be the best tool. You cannot measure the volume directly. First, measure the length, width and height with the ruler and use the formula of volume of cubiod (L x W x H)
