Fig. shows a square tapered pedestal
for a statue. Workout the quantity of plaster provided on battered surface.
Square Tapered pedestal
Solution :
The geometrical shapes of the
battered surface are of trapezoidal shape and all the form sides have equal
surface areas.
The slant height of the square
tapered pedestal is the height between the top and bottom edge of the trapezoidal.
Therefor,
= 10
= 3.162
Now the total surface of all
four sides,
= 4 x (1+3 / 2) x 3.142
= 25.136 sq.m.
