Answer:
front: 30 cm²
back: 30 cm²
right: 30 cm²
left: 30 cm²
bottom: 25 cm²
top: 25 cm²
top: 5 cm × 5 cm = 25 cm²
TOTAL: 170 cm²
Step-by-step explanation:
Since the face of the blue prism is either in rectangular or in square shape,
we can use formula to find each face area:
[tex]\boxed{\boxed{\sf Area = Length \times Width }}[/tex]
Using this, we get
front: 6 cm × 5 cm = 30 cm²
back: 6 cm × 5 cm = 30 cm²
right: 6 cm × 5 cm = 30 cm²
left: 6 cm × 5 cm = 30 cm²
bottom: 5 cm × 5 cm = 25 cm²
top: 5 cm × 5 cm = 25 cm²
TOTAL Area: Area of ( font + back + right+ left + bottom + top )
= (30 + 30 + 30 + 30 + 25 + 25) cm²
= 170 cm²
Therefore, the total surface area of the blue prism is:
170 cm²
