Answer:
l = 15, m, b = 10 m and h = 7m Total surface area of room = 2 (lb + bh + hl) \[=2\left( 15\times 10+10\times 7+7\times 15 \right)\] \[=2\left( 150+70+105 \right)\] \[=650\text{ }{{m}^{2}}\] Area of floor \[=\text{ }l\times b\] \[=15\times 10=150\text{ }{{m}^{2}}\] Area painted by Daniel \[=650150\] \[=\text{ }500\text{ }{{m}^{2}}\] \[\therefore \,\,\,\,100\text{ }{{m}^{2}}\]area painted by 1 can \[\therefore \,\] 500 \[{{m}^{2}}\] area painted \[=\frac{1}{100}\times 500\] = 5 cans.
