<span>P = 2l + 2w
The given values fit the given formula</span>
The given values are 134
Let L = 5 - w
Solution:
P = 2l + 2w
134 = 2(5-w) + 2w 134 = 10-2w + 2w 134 – 10 = 4w 124 = 4w
31 = w
<span>26 = l</span>

answer is A. first one
Answer:
x=1000
Step-by-step explanation:
I think it’s the first answer choice
Given:
Volume of rectangular prism: width * height * length
Surface area of rectangular prism : 2(wl + hl + lw)
A.
<span>8 ft by 5 ft by 6 ft; </span>⇒ <span>V = 240 ; S.A = 236</span>
5 ft by 6 ft by 8 ft; ⇒ V = 240 ; S.A = 236
B.
<span>8 ft by 5 ft by 6 ft; </span>⇒<span> V = 240 ; S.A. = 236</span>
10 ft by 8 ft by 3 ft ⇒ V = 240 ; S.A = 268
THIS IS THE ANSWER. SAME VOLUME: DIFFERENT SURFACE AREA.
C.
<span>15 ft by 8 ft by 2 ft; </span>⇒ <span>V = 240 ; S.A = 332</span>
6 ft by 4 ft by 15 ft ⇒ V = 360 ; S.A = 348
D.
<span>12 ft by 6 ft by 5 ft; </span>⇒<span> V = 360 ; SA = 324</span>
<span>8 ft by 10 ft by 3 ft </span>⇒ <span>V = 240 ; SA = 268 </span>
