What is the surface area of the solid?

Paha777 [63]

Answer:

D. 28 square centimeters

Step-by-step explanation:

The surface area of the prism is the sum of the base areas and the lateral area. Here, the base is an odd shape, so it must be decomposed into shapes we can find the area of.

The base of this prism is the L-shaped face nearest the observer. It can be decomposed into a 1 cm square atop a 1 cm by 3 cm rectangle. The area of the face is the sum of the areas of these parts.

square area = s² . . . . where s is the side length

= (1 cm)² = 1 cm²

rectangle area = bh . . . . b is the base, h is the height

= (3 cm)(1 cm) = 3 cm²

Then the area of the one prism base we see is ...

base area = 1 cm² +3 cm² = 4 cm²

The total area of both L-shaped bases of the prism is ...

total base area = 2(4 cm²) = 8 cm²

<h3>lateral area</h3>

The perimeter of the base is the sum of the lengths of its edges. Working clockwise from the lower left corner, we find the base perimeter to be ...

(1 +2 +1 +1 +2 +3) cm = 10 cm

The lateral area is the product of the "height" of the prism (the distance between the parallel bases) and this perimeter length.

LA = Ph

LA = (10 cm)(2 cm) = 20 cm²

<h3>solid area</h3>

The surface area of the solid is the sum of the areas of the bases and the lateral area:

total surface area = total base area + LA

= (8 cm²) +(20 cm²) = 28 cm²

The surface area of the solid is 28 square centimeters.

60 vehicles parked on the driveway 1/4 of them were trucks. How many trucks?

Sidana [21]

Answer:

15 trucks

Step-by-step explanation:

If there are a total of 60 vehicles, and 1/4 of them are trucks, we can multiply 60 by 1/4 to get our answer. Or because 1/4 is split into fourths, we can divide 60 by 4 to also get our answer.

Hope this helps!

SVETLANKA909090 [29]

Answer: The required probability is 0.1923.

Step-by-step explanation:

Since we have given that

Probability that it's a good dog = 0.4

Probability that it's a bad dog = 1-0.4 = 0.6

Probability that the dog smokes given that its a bad dog = 0.7
