Answer:
Step-by-step explanation:
Area of wall = lh + lh + bh + bh = 2lh + 2bh = 2h *(l + b)
Area of ceiling = lb
Area of wall and ceiling = 2h(l +b) + lb
= 2*8* (20 +15) + 20*15 = 16*35 + 20*15
= 560 + 300 = 860
Cost of painting per m^2 =20/10 = 2
Cost of painting 860 m^2 = 860 * 2 = 1720
Volume = l * b *h = 20 * 15 * 8 = 2400 m^3
