Answer 1

Answer:

TSA of cuboide is =2(lh +bh+bl)

= 2×10×6 +2×6×5 +2×5×10

= 120+60+100

= 280 m square

area of wall and sealing = 280 - 60

= 220 m square

area of door and windows = (1.5 ×2)+(1.8×2)

=3 + 3.6

=6.6 m square

area of wall and sealing without door and windows

= 220-6.6

=213.4 m square

cost =213.4 × 50

= Rs. 106070 answer
