The surface area of the geometric shape is B. 840 cm².
Step-by-step explanation:
Step 1:
The given figure is made up of three rectangles and two triangles.
The surface area of the geometric shape is given by summing the individual surface areas.
The geometric shape's surface area = The sum of the individual surface areas.
Step 2:
The surface area of the rectangles is the multiplication of its length and width.
The surface area of the rectangle with length z and width x
.
The surface area of the rectangle with length y and width x
.
The surface area of the rectangle with length x and width x
.
Step 3:
The area of a triangle is half the product of its base length and height.
The surface area of a triangle with base y and height x
.
They are two similar triangles so their areas are equal
Step 4:
The geometric shape's surface area
.
So the surface area is option B. 840 cm².
Answer:
1.1995
2.114.4
3.270
Step-by-step explanation:
1. Multiply the length and width
2. Multiply 14.3*8
3. Multiply 15*36 and divide the product by 2
to find the area of a rectangle, multiplty length times width
for the area of a triangle, multiply the bottom of the triangle by the height and divide it by 2.
There is a 2/3 probability. Why? Well, the cube is numbered 1-6 so that is 6 numbers. Out of 6, there are 4 numbers greater than 2. Because of this, there is a 4/6 probability that a number greater than 2 will be rolled. 4/6 reduces to 2/3. As a percentage and decimal, the probability would be 66.66666666% or 0.66666666666 (repeating).
