Triangular Prism- SA= 1/2bh
= 1/2 × 7 × 11
= 38 1/2 × 4 = 154
7 × 7 = 49
= 154 + 49
= 204in³
Rectangular Prism- SA= 2lw + 2lh + 2wh
= 2 × 11 × 7 + 2 × 11 × 7 + 2 × 7 × 7
= 154 + 154 + 98
= 406in³
Therefore, the rectangular prism has the larger surface area.
Answer:
2,058
Step-by-step explanation:
first term : a_1 = 6
common ratio r = 7
a_n = (a_1) * r ^(n-1)
a_4 = 6 * 7^(4-1)
a_4 = 6 *7^3
a_4 = 6 * 343 = 2,058
Answer:
3 cm
Step-by-step explanation:
That's two half lives. 5/8 * 2 * 2 = 20/8 = 5/2 pounds7/8 * 2 * 2 = 28/8 = 7/2 pounds
