Question

Kate is painting a ceramic paperweight shaped like a rectangular prism, as shown here. (dimensions of .8 ft , 1.2 ft, 1.2 ft)She wants to find the surface area of the paperweight so she can determine how much paint she needs.
The area of one of the bases is _____
The area of each lateral rectangular face is _____
The surface area of the paperweight is _____

Answer 1

Answer:

area of one of the basses is 1.44 square feet

area of each lateral rectangular face is 0.96 square feet

SURFACE AREA OF THE PAPERWEIGHT IS 6.72 square feet.

Step-by-step explanation:

Answer 2

Answer:

The area of one of the bases is 0.96 ft²

The area of each lateral rectangular face is 4.8 ft²

The surface area of the paperweight is 6.72 ft²

Step-by-step explanation:

we know that

The surface area of the rectangular prism is equal to

SA=2B+LA

where

B is the area of one of the bases

LA is the lateral area of the prism

Find the area of one of the bases B

B=(0.8)(1.2)=0.96 ft²

Find the lateral area LA

The lateral area is the area of each lateral rectangular face

LA=2[(0.8)(1.2)]+2[(1.2)(1.2)]=4.8 ft²

Find the surface area

SA=2(0.96)+4.8=6.72 ft²
