Thermochemistry : Comparing Heat Capacity of Bricks and Water

A house is designed to have passive solar energy features. Brickwork incorporated into the interior of the house acts as a heat absorber. Each brick weighs approximately 1.8 kg. The specific heat of the brick is 0.85 J/g-K. How many bricks must be incorporated into the interior of the house to provide the same total heat capacity as 1.7 x 10^3 gal of water?** 10^3 (ten to the power of 3)
