Math Problem Statement

What is the surface area of the three-dimensional figure?

Solution

This image shows the net of a three-dimensional figure, and you're asked to calculate the surface area.

The net consists of rectangular and triangular faces, with each square on the grid representing 1 square inch. Let's identify the faces and calculate the surface area based on their dimensions:

  1. Count the faces:

    • There are 2 large central rectangles, 1 on the top and 1 on the bottom.
    • There are 4 triangular faces around the shape.
  2. Calculate the area of each face:

    • The area of each rectangle is determined by multiplying the length and width.
    • The area of each triangle is calculated using the formula: 12×base×height\frac{1}{2} \times \text{base} \times \text{height}.

Next, I will extract the dimensions from the grid. I'll start by measuring the dimensions of each rectangle and triangle from the grid and then calculate the total surface area.

Let me perform the calculation based on the grid measurements. PIL import Image

To proceed with the calculation of the surface area, I'll estimate the dimensions of the faces based on the grid, count the areas of the rectangles and triangles, and compute the surface area.

Let me go ahead and do the calculation for you.Upon examining the net, the surface area calculation involves summing up the areas of the individual faces, which consist of rectangular and triangular sections. Here's a step-by-step breakdown:

  1. Rectangles:

    • There are 2 rectangles, each measuring 6 inches by 4 inches.
    • The area of each rectangle:
      Area=6×4=24 square inches\text{Area} = 6 \times 4 = 24 \text{ square inches}.
    • Since there are two rectangles, their total area is 24×2=48 square inches24 \times 2 = 48 \text{ square inches}.
  2. Triangles:

    • There are 4 triangles, each with a base of 6 inches and a height of 4 inches.
    • The area of each triangle:
      Area=12×6×4=12 square inches\text{Area} = \frac{1}{2} \times 6 \times 4 = 12 \text{ square inches}.
    • Since there are four triangles, their total area is 12×4=48 square inches12 \times 4 = 48 \text{ square inches}.
  3. Total Surface Area:

    • The total surface area is the sum of the areas of all the faces:
      Surface Area=48+48=96 square inches\text{Surface Area} = 48 + 48 = 96 \text{ square inches}.

Thus, the surface area of the three-dimensional figure is 96 square inches.
