Math Problem Statement

What is the volume of a prism with a right triangular base where the triangle has a base of 10 cm, height of 8 cm, and the prism height is 15 cm?

Solution

The image presents a right triangular prism with the dimensions of its triangular base and height specified. Let's calculate the volume of the prism step by step.

Information from the image:

  • The base of the triangle (AB) = 10 cm
  • The height of the triangle (AC) = 8 cm
  • The height of the prism (DE or EF) = 15 cm

Formula to find the volume of a triangular prism:

Volume=Area of the triangular base×Height of the prism\text{Volume} = \text{Area of the triangular base} \times \text{Height of the prism}

Step 1: Find the area of the triangular base

The triangular base is a right triangle, so its area is calculated as: Area of triangle=12×base×height\text{Area of triangle} = \frac{1}{2} \times \text{base} \times \text{height} Area=12×10cm×8cm=40cm2\text{Area} = \frac{1}{2} \times 10 \, \text{cm} \times 8 \, \text{cm} = 40 \, \text{cm}^2

Step 2: Calculate the volume

Now, using the height of the prism (15 cm): Volume=40cm2×15cm=600cm3\text{Volume} = 40 \, \text{cm}^2 \times 15 \, \text{cm} = 600 \, \text{cm}^3

Answer:

The volume of the triangular prism is 600 cm³. However, this value doesn't match any of the provided options. It seems there might be an issue with the provided options or the dimensions, as none of the choices (240 cm³, 180 cm³, 300 cm³, 360 cm³) corresponds to this calculation.
