Find the CSA DE cuboid, L=15m, and h=6m,
Answers
Step-by-step explanation:
It is given that length =15 m, breadth 6 m and height =5 cm=0.5 m
We know that
Volume of cuboid =1×b×h
By substituting the value we get
Volume of cuboid =15×6×0.5
By multiplication
Volume of cuboid =45 m
3
We know that
Lateral surface of a cuboid =2(1+b)×h
By substituting the values
Lateral surface area of a cuboid =2(15+6)×0.5
On further calculation
Lateral surface area of a cuboid =2×21×0.5
By multiplication
Lateral surface area of a cuboid =21 cm
2
We know that
Total surface area of cuboid =2(Ib+bh+Ih)
By substituting the value
Total surface area of cuboid =2(15×6+6×0.5+15×0.5)
On further calculation
Total surface area of cuboid =2(90+3+7.5)
So we get
Total surface area of cuboid =2×100.5
By multiplication
Total surface area of cuboid =201 m

Answer:
It is given that length = 15 m, breadth 6 m
and height = 5 cm = 0.5 m
We know that
Volume of cuboid = 1 xbxh
By substituting the value we get
Volume of cuboid-15×6×0.5
By multiplication
Volume of cuboid 45 m²
We know that
Lateral surface of a cuboid=2(1+b) x h
By substituting the values
Lateral surface area of a cuboid=2(15+
6) x 0.5
On further calculation
Lateral surface area of a cuboid = 2 x
21 x 0.5
By multiplication
Lateral surface area of a cuboid = 21 cm²
We know that
Total surface area of cuboid=2(1b + bh+Ih)
By substituting the value
Total surface area of cuboid=2(15 x 6+ 6 x 0.5 + 15 x 0.5)
On further calculation
Total surface area of cuboid 2(90+3+
7.5)
So we get
Total surface area of cuboid = 2 × 100.5
By multiplication
Total surface area of cuboid - 201 m²
