Find the surface area of the composite figure.
Sloan [31]

With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.

<h3>What is the surface area of a truncated prism?</h3>

The <em>surface</em> area of the <em>truncated</em> prism is the sum of the areas of its six faces, which are combinations of the areas of rectangles and <em>right</em> triangles. Then, we proceed to determine the <em>surface</em> area:

A = (12 cm) · (4 cm) + 2 · (3 cm) · (4 cm) + 2 · (12 cm) · (3 cm) + 2 · 0.5 · (12 cm) · (5 cm) + (5 cm) · (4 cm) + (13 cm) · (4 cm)

A = 48 cm² + 24 cm² + 72 cm² + 60 cm² + 20 cm² + 52 cm²

A = 276 cm²

With the help of the <em>area</em> formulae of rectangles and triangles and the concept of <em>surface</em> area, the <em>surface</em> area of the composite figure is equal to 276 square centimeters.

Directions: Match the product and quotients estimates below with the correct expression on the left
prohojiy [21]

Answer:

Answer is in attached image.

Step-by-step explanation:

Given the expressions, for which we have to find the estimates as per the expressions on the left.

The given expressions are:

1) 35 \times 23

2) 132 \div 168

3) 17.3 \times 18.4

4) 999 \div 208

5) 998 \times 211

Here, we need to find the rounded off numbers.

35 can be rounded to 40 and 23 to 20.

Therefore, equivalent to 35 \times 23 is 40 \times 20

132 can be rounded to 130 and 168 to 170.

Therefore, equivalent to 132 \div 168 is 130 \div 170.

17.3 can be rounded to 17.0 and 18.4 to 18.0.

Therefore, equivalent to 17.3 \times 18.4 is 17.0 \times 18.0.

999 can be rounded to 1000 and 208 to 210.

Therefore, equivalent to 999 \div 208 is 1000 \div 210.

998 can be rounded to 1000 and 211 to 210.

Therefore, equivalent to 998 \times 211 is 1000 \times 210.

The solution can be found in the attached image as well.
