A rectangular solid has sides of 4 cm, 6 cm, and 8 cm. What is its surface area?
Solution:
Given, a rectangular solid of sides 4cm, 6cm and 8cm.
We have to find the surface area of a rectangular solid.
The surface area of a rectangular solid is given by
A = 2(xy + yz + zx)
Where, x, y and z are the dimensions of the rectangular solid.
Here, x = 4, y = 6 and z = 8.
Surface area, A = 2[(4 × 6) + (6 × 8) + (8 × 4)]
A = 2[24 + 48 + 32]
A = 2[104]
A = 208 square centimeters.
Therefore, the surface area of rectangular solid is 208 square centimeters.
A rectangular solid has sides of 4 cm, 6 cm, and 8 cm. What is its surface area?
Summary:
A rectangular solid has sides of 4cm, 6cm and 8cm. Its surface area is 208 square centimeters.
