For this question, consult the following figure of a rectangular solid. Identify this solid (i.e., what type of solid is it). Explain your reasoning. How many edges does this solid have? How many of the edges are perpendicular to BC? Suppose AB = 12 cm, BC = 4 cm, and BD = 5 cm. What it the surface area of the solid? A student writes the following for the division of 9893 by 47: Explain why this algorithm works (if it works at all). Use this algorithm to divide: 5793 26.

Solution

10.(a) . cuboid, because to cover whole solid we need rectangular sheets.

(b) 12 edges as there are 12 line segments.

(c) 4, 2 perpendicular at B and 2 at C.

(d) Surface Area of a Cuboid = 2(lb + bh + hl)=2(12x4+12x5+4x5)=256 cm^2
