Total Surface Area Of The Cuboid = 1160 cm^2
Lateral Surface Area Of The Cuboid = 560 cm^2
Given:
Length of the cuboid (l) = 20 cm
Breadth of the cuboid (b) = 15 cm
Height of the cuboid (h) = 8 cm
To Find:
Lateral Surface Area Of The Cuboid
Total Surface Area Of The Cuboid
Calculating:
Formula that is used to calculate the lateral surface area of a cuboid:
= 2h(l + b)
Substituting all the values known to us in this formula we get:
= 2 x 8 x (20 + 15)
= 16 x 35
= 560 cm^2
Therefore, the lateral surface area of the cuboid is 560 cm^2.
Formula that is used to calculate the total surface area of the cuboid:
= 2(lb + lh + bh)
Substituting all the values known to us in this formula we get:
= 2((20)(15) + (8)(20) + (15)(8))
= 2(300 + 120 + 160)
= 2 x 580
= 1160 cm^2
Therefore, the total surface area of the cuboid is 1160 cm^2.
