Q.1

What is the quantity (Sq.m) of plastering required for the 6m length of wall which is 4m high and 50 cm thick ?

6 मीटर लंबी, 4 मीटर ऊंची और 50 सेमी मोटी दीवार पर प्लास्टर करने के लिए कितनी मात्रा (वर्ग मीटर में) की आवश्यकता होगी?
A

24
C

Answer ( Option C)

48

Solution

Area for plastering = Length of wall x Height of wall

= 4 × 6 = 24 m2

Since plastering will be done on both sides of wall

Hence quantity (in Sq. m) of plastering = 24 × 2 = 48 m2
