The dimensions of a cuboid are 12cm,8cm,5cm
The find the lateral surface area and total surface area?
Answers
Answer:
Step-by-step explanation:
the box is a cuboid,
length of cuboid = 12 cm
breadth = 8 cm
height = 5 cm
total surface area of cuboid = 2( lb + bh+ hl )
= 2( 12×8 +8×5 +12×5)
= 2× 196
= 392 cm²
or if you want to find out lateral surface area
LSA of cuboid = 2h (l+ b)
= 2×5 (12 +8)
= 10 (20)
= 200 cm²
Given:
The dimensions of a cuboid are 12cm,8cm,5cm
To find:
find the lateral surface area and total surface area?
Formula used:
Total surface area of cuboid = 2 ( lb + bh + hl )
Lateral surface area = 2h ( l + b )
Solution:
Total surface area of cuboid = 2( lb + bh+ hl )
= 2( 12×8 +8×5 +12×5)
= 2× 196
= 392 cm²
Lateral surface are of cuboid = 2h (l+ b)
= 2×5 (12 +8)
= 10 × 20
= 200 cm²
