In A Building There Are 5 Rooms. Each Having A Equal Area .the Length Of The Room Is 4m And Bread Ht Is 5 M.the Height Of The Rooms Are 2m.if 17 Bricks Are Needed To Make A Square Meter Then How Many Bricks Are Needed To Make The Floor Of A Particular Room?

Answer»

Dimensions = 4 X 5 x 2

TSA = 2 (4 x 5 + 5 x 2 + 4 x 2) = 2(20+10+8)=2x38 = 76 sq m

So BRICKS REQUIRED = 76 x 17 = 1292

For 5 rooms 1292 x5 = 6460

Dimensions = 4 x 5 x 2

TSA = 2 (4 x 5 + 5 x 2 + 4 x 2) = 2(20+10+8)=2x38 = 76 sq m

So bricks required = 76 x 17 = 1292
