A student found the surface area of this pyramid.
Surface area = (12)6) + 2(12)(8) +2 (6)(9.5)
= 72 +48 + 28.5
= 148.5cm
What error did the student make?
The student should have used the same value for
all of the triangular faces.
The student added only three of the five faces.
O The student did not use the correct formula to find
the area of the triangular faces.
The student did not find the correct area of the
rectangular base.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
