Sagot :
Answer:
6
Step-by-step explanation:
We firat gotta calculate the surface area of the walls and the ceiling
Walls
(25 × 8) m2 × 2
=200m2 × 2
=400m2
(25 × 12)m2 × 2
=300m2 × 2
=600m2
We have to times it by 2 because there is 2 walls
Ceiling
(12 × 8) m2
=96m2
Total
400m2 + 600m2 + 96m2
=1096m2
Cans needed
1096m2 ÷ 200m2 = 5 remainder of 96
Remainder becomes another can so
5 + 1 = 6
Answer:
LSA of a cuboid = 2(l+b) h
= 2×( 25+12) 8
= 592m square
how many cans reqired?
1 can = 200 m sq
therefore, 592 msq = 592÷200
= 2.96
