I m getting 308.11, there is an additional 0.60 that is added, maybe your source is wrong, or there is a copying error.

I Need Help With This:​

Answer:

1. a) 8 cm × 8 cm = 64 sq cm

b) (64 cm²) × 6 squares = 384 sq cm

2. 152 sq cm

Step-by-step explanation:

1. The area of any rectangle is the product of its length and width. For a square, length and width are the same. The square faces of your die have length and width of 8 cm, so the area is (8 cm) × (8 cm) = 64 sq cm.

A cube has 6 faces of identical size, so the total surface area is 6 times the area of one face. Your cube's surface area is 6 × 64 sq cm = 384 sq cm.

___

2. A rectangular prism (cuboid) has 6 faces—3 pairs that are the same size. The area is the total of the areas of these pairs of faces. It can be computed by ...

A = 2(LW + WH + LH)

For your rectangular prism, this is ...

A = 2((8 cm)×(6 cm) + (6 cm)×(2 cm) + (8 cm)×(2 cm))

= 2(48 sq cm + 12 sq cm + 16 sq cm)

= 2×(76 sq cm)

= 152 sq cm
