A hall is 15 m long and 12 m broad. If the sum of the areas of the floor and the ceiling is equal to the sum of the areas of four walls, the volume of the hall is:
720
900
1200
1800
Explanation:
2(15 + 12) x h = 2(15 x 12)
=> h = $\dfrac{180}{27}m = \dfrac{20}{3}m$
ą®Volume = $(15 \times 12 \times \dfrac{20}{3})m^3 = 1200 m^3$
2(15 + 12) x h = 2(15 x 12)
=> h = $\dfrac{180}{27}m = \dfrac{20}{3}m$
ą®Volume = $(15 \times 12 \times \dfrac{20}{3})m^3 = 1200 m^3$
