Answer:
158 m²
Step-by-step explanation:
Get the area of all the faces, then add them
2(8 x 3) = 48
2(3 x 5) = 30
2(8 x 5) = 80
48 + 30 + 80 = 158
Answer:
194 and 66
Step-by-step explanation:
Represent the numbers by a and b.
Then a + b = 260 and a = 3b - 4.
Substitute 3b - 4 for a in the first equation. Then:
3b - 4 + b = 260, and:
4b = 264, which works out to b = 66. If b = 66, then a = 3(66) - 4 = 194.
The two numbers are 194 and 66.
