Answer:
232 in^2
Step-by-step explanation:
Using the formula for surface area A=2(wl+hl+hw)
A=2(16+80+20)
A=232
The surface area of the cereal box is 232 square inches
The surface area of a cuboid is the total area of all its surfaces. Since a cuboid is a three-dimensional solid shape, the value of its surface area depends on the dimensions of its length, width, and height. The change in any of the dimensions of a cuboid changes the value of the surface area of a cuboid. The surface area of a cuboid is expressed in square units.
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
According to the question
A cereal box has a height = 10 inches
A cereal box has a length = 8 inches
A cereal box has a width = 2 inches
Now ,
Applying the formula of Total Surface Area of Cuboid as cereal box is also a cuboid
Total Surface Area of Cuboid
= 2 (length*width + width*height + length*height)
substituting the values
Total Surface Area of Cuboid
= 2 (8*2 + 2*10 + 8*10)
= 2 (16 + 20 + 80)
= 2(116)
= 232 square inches
Hence, the surface area of the cereal box is 232 square inches
