Find the surface area of each figure. Round your answers to the nearest hundredth, if necessary.

Ira Lisetskai [31]

Answer:

Step-by-step explanation:

The given figure is an hexagonal pyramid. It has a hexagonal base and six triangular lateral faces. The formula for determining the surface area of the pyramid is expressed as

Surface area = 3ab + 3bs

Where

a represents the apotherm which is the distance from each side of the hexagon to the center.

b represents the base length

s represents the slant height of the hexagonal base.

From the information given,

a = 5.2 cm

b = 6 cm

s = 12.2 cm

Surface area = (3 × 5.2 × 6) + (3 × 6 × 12.2) = 93.6 + 219.6 = 313.2 cm²

A pentagonal prism has a base area of 124 square inches. The lateral area (area of the sides) is made up of 5 equal-sized rectan

wel

The surface area of the pentagonal prism is 648 square inches.

Step-by-step explanation:

Step 1:

The surface area of a shape is the sum of all the areas of all the external surfaces.

The pentagonal prism has a total of 7 sides i.e. 2 pentagonal sides and 5 rectangular sides.

The total surface area of the prism is the sum of the individual areas of the 7 sides.

Step 2:

The area of the 2 pentagonal sides $= 2(124) = 248$ square inches.

The area of each rectangular side is 80 square inches. So

The area of 5 rectangular sides $= 5(80) = 400$ square inches.

The total surface area of the prism $=248+400 = 648$ square inches.

The surface area of the pentagonal prism is 648 square inches.
