Answer:

40.5 in²

Explanation:

Formula applied :

Surface Area (rectangular prism)

2(Length × Width + Width × Height + Length × Height)

=============================================================

Given :

⇒ Length = 6 inches

⇒ Width = 1.5 inches

⇒ Height = 1.5 inches

============================================================

Solving :

⇒ Surface Area = 2(6 × 1.5 + 1.5 × 1.5 + 6 × 1.5)

⇒ Surface Area = 2(9 + 2.25 + 9)

⇒ Surface Area = 2 × 20.25

⇒ Surface Area = 40.5 in²

#2

The shape can be cut into four rectangles and two squares.

Total surface area:

⇒ four rectangles + two squares

⇒ 4(Length × Width) + 2(side × side)

⇒ 4(6 × 1.5) + 2(1.5 × 1.5)

⇒ 36 + 4.5

⇒ 40.5 inch²

Therefore, the surface area of the rectangular prism is 40.5 inch²

#3
