Math Problem Statement

Perhatikan gambar prisma segitiga di bawah ini! Volume prisma segitiga tersebut adalah?

Solution

To solve for the volume of the triangular prism shown in the image:

The formula for the volume of a triangular prism is: V=Base Area×Height of the prismV = \text{Base Area} \times \text{Height of the prism}

Step 1: Calculate the base area of the triangle

The triangle's base is 7 cm, and its height is 25 cm. The formula for the area of a triangle is: Base Area=12×Base×Height\text{Base Area} = \frac{1}{2} \times \text{Base} \times \text{Height} Base Area=12×7×25=87.5cm2\text{Base Area} = \frac{1}{2} \times 7 \times 25 = 87.5 \, \text{cm}^2

Step 2: Multiply by the height of the prism

The height of the prism is given as 30 cm. Substituting into the formula for volume: V=87.5×30=2625cm3V = 87.5 \times 30 = 2625 \, \text{cm}^3

However, the correct choice marked in the question is 2320 cm³. There might be a clarification needed for the exact dimensions or assumptions, as this result conflicts with the provided answer.
