The first answerer is quite wrong. a) Granite can become a sandstone through weathering and b) Granite is NOT a metamorphic rock. It is igneous.
Refer to your rock cycle. Igneous and metamorphic rocks can weather to form sedimentary rocks. Sedimentary rocks and and Igneous rocks can metamorphose. Sedimentary rocks and metamorphic rocks can melt to become igneous rocks.
The granite can be weathered down over time, usually weathered until mostly quartz and feldpsars remain, and then it is lithified into a sandstone or an arkose sandstone (one that is quartz and potassium feldspar).

when granite is eroded or broken down into small sand sized peices and then reformed into sandstone through pressure and heat....its all part of hte rock cycle

It can't it's the other way around. after a long period of time sandstone (a sedimentary rock), under great heat and pressure becomes granite (a metamorphic rock)
