Vladimir [108]

Answer:

The answer to your question is 236 ft²

Step-by-step explanation:

Data

height = 5 ft

width = 6 ft

length = 8 ft

Area = ?

Process

I will consider that the crate is a rectangular prism which has 6 sides

1.- Find the area of the sides that measure 8 x 6

Area = 2 (8 x 6)

        = 2(48)

        = 96 ft²

2.- Find the area of the sides that measure 8 x 5

Area = 2(8 x 5)

Area = 2(40)

Area = 80 ft²

3.- Find the area of the sides that measure 6 x 5

Area = 2( 6 x 5)

Area = 2(30)

Area = 60

4.- Find the total area

Area = 96 + 80 + 60

Area = 236 ft²

5.- Conclusion

She needs 236 ft² of paint
