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
The polygons that would be used in this net surface area are:
✔ rectangle
✔ square
Answer:
40.5 in²
Step-by-step 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
