Answer:
528 cm²
Step-by-step explanation:
The surface area of this prism comprises:
- 2 congruent triangles (the bases of the prism)
- 2 congruent rectangles (rectangle 1 and 2) - since the triangle has 2 sides of equal length
- 1 rectangle (rectangle 3)
Area of a triangle = 1/2 × base × height
= 1/2 × 16 × 6
= 48 cm²
Area of rectangle 1 / 2 = width × length
= 10 × 12
= 120 cm²
Area of rectangle 3 = width × length
= 16 × 12
= 192 cm²
Total Surface Area = 2 triangles + 2 rectangles + rectangle 3
= (2 × 48) + (2 × 120) + 192
= 96 + 240 + 192
= 528 cm²

Answer:
The number of protons is the answer
Answer:
x = 34
Step-by-step explanation:
Add x+24 to both sides of the equation and simplify.
2 + 8 - x + x + 24 = -24 + x + 24
34 = x
98.
The numbers increase by intervals of 8. You need 16 more terms until you reach the 20th term, so 16*8=128.
128-30=98.
