Answer:

  • surface area: 456 cm²
  • volume: 408 cm³

Step-by-step explanation:

The surface area of the figure is the total of the areas of the two triangular bases and the three rectangular faces.

  SA = 2(1/2)(8 cm)(6 cm) + (17 cm)(6 cm + 8 cm  + 10 cm)

  = 48 cm² + 408 cm²

  SA = 456 cm²

__

The volume is the product of the area of the triangular base and the length of the prism.

  V = (1/2)(8 cm)(6 cm)×(17 cm) = (24 cm²)(17 cm)

  V = 408 cm³

Answer:

12.4 cm³

Step-by-step explanation:

From the picture attached,

Radius of the circular top of the cone = \frac{\text{Diameter}}{2} = \frac{2}{2}=1

Height of the cone = h

Lateral height of the cone = h

By applying Pythagoras theorem in the right triangle of the cone,

l² = r² + h²

6² = 1² + h²

h = \sqrt{36-1}

h = \sqrt{35}

Ice cream needed to fill one cone = Volume of the cone

Since, formula for the volume of the cone V = \frac{1}{3} \pi r^{2} h

V = \frac{1}{3}\pi (1)^2(\sqrt{35})

   = 6.195

   ≈ 6.20 cm³

Ice cream needed to fill the two cones = 2 × 6.20

                                                                 = 12.4 cm³

Therefore, ice cream needed to fill the two cone = 12.4 cm³
