Answer: 108 cm squared
Step-by-step explanation: To find the lateral area, you have to multiply the perimeter of the base by the height of the rectangular prism.
1. Perimeter: 10 + 10 + 8 + 8 = 36
2. Lateral area: 36 * 3 = 108

Answer:
5/6 times (4 - 3x)
Step-by-step explanation:
The sum of 3a²-a-3 and 2a-9 is 3a²+a-12
3a²+a-12 - (a²-3a-7) = 3a²+a-12 - a² + 3a + 7 =
2a² +4a - 5
Answer:
75cm^2
Step-by-step explanation:
When you say a rectangular prism, it means it has the base has 4 sides of which opposite sides are equal as a rectangle. This sides substends so we have a total of 6 surfaces in this prism.
This 6 surfaces has 3 surface area the same.
The surface area = sum of area of all faces.
325= 50 + 50 + 37.5 + 37.5 + 2x; where X is the area of the surface unknown.
325= 100+ 75 + 2x
325-175= 150
150= 2x
X= 150/ 2 = 75 cm^2
Answer:
The pattern is that they are multiplying by -3 every time. 81*-3 = -243
