Which of the following is the
side elevation of the given shape?
We can recall that an elevation
is a two-dimensional drawing of a three-dimensional shape. We can say, therefore, that the
side elevation is a two-dimensional drawing of a three-dimensional shape when
viewed from the side. In this type of question, we’ll
usually be given the direction to take as the side. It can be easy to get confused
between elevations and plans, but plans are different in that they’re a
two-dimensional drawing from above. In this question, however,
let’s look for the side elevation. If you find visualizing this
type of activity difficult, it can be useful to shade what we might see.
We might find it a little bit
easier to realize that we see the sides of these four blocks on the base of the
shape; however, we’d also see the side of these two blocks at the top of the
shape. When it comes to adding these
two blocks into our side elevation, although in the diagram we can see that
they’d be set further back from the four on the base, when it comes to drawing
them, we’d just draw these two blocks on top of the other four. Therefore, we’d have a
rectangle two units along and three units up. Therefore, the answer is that
given in option (B), and none of the other options would fit with the side
elevation.
However, let’s take a quick
look at option (A). This is, in fact, that the
front elevation of the shape as it’s the two-dimensional drawing when viewed
from the front. If we look at the
two-dimensional drawing in option (C), that’s the plan view because if we looked
down on this three-dimensional shape from above, we’d see a rectangle that’s
four units long by two units long. But as neither of these nor
options (D) or (E) give us the side elevation, then we can give our answer as
option (B).
