Answer:
- small prism: 630 m²
- large prism: 2520 m²
Step-by-step explanation:
The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.
For the smaller prism, the area is ...
(20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²
The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:
4×630 m² = 2520 m²
__
In summary, the total surface area of each prism is ...
- small prism: 630 m²
- large prism: 2520 m²
Answer:
125 cm3
Step-by-step explanation:
V = l * w * h
V = 5 * 5 * 5
V = 125 cm3
The estimated sum of the numbers fifty-eight (58) and twenty-nine (29) is equal to ninety (90).
<h3>What is the difference between a regular sum and an estimated sum?</h3>
In an estimated sum, the numbers are rounded; on the other hand, in a regular sum, the numbers are not changed.
<h3>What is the estimated sum of 58 and 29?</h3>
1. Round the numbers:
- 58 = 60 as this number is nearest to 60 than to 58.
- 29= 30 because of the same reason explained above.
2. Add the rounded numbers:
