Give (i) an oblique sketch and (ii) an isometric sketch for each of the following:An isometric sheet is attached at the end of the book. You could try to make on it some cubes or cuboids of dimensions specified by your friend. A cuboid of dimensions 5 cm, 3 cm and 2 cm. (Is your sketch unique?)

Three cubes each with 2 cm edge are placed side by side to form a cuboid. Sketch an oblique or isometric sketch of this cuboid

(Street Plan): A city has two main roads which cross each othe at the centre of the city. These two roads are along the North-Sout! direction and East-West direction. All the other streets of the city ru parallel to these roads and are 200 m apart. There are about 5 streets i eacha direction. Using 1 cm = 200 m, draw a model of the city on you notebook. Represent roads/streets by single lines. There are many cross-streets in your model. A particular cross treet is måde by two streets. One running in the North-South direction nd another in the East-West direction. Each crossstreet is referred to in the following manner: If the 2nd street running in the North-south direction and 5th in the East-West direction meet at some crossing, then ve will call this cross-street (2,5). Using this convention, find : (i) how many cross-streets can be referred to as (4,3) (ii) how many cross-streets can be referred to as (3,4).
