Answer:
If it is a rectangular prism (this formula only works with that 3d shape, the answer is 2016 cm²
Step-by-step explanation:
SA=2(hl+hw+lw)
SA=2(18×19+18×18+18×19)
Sa=2(342+324+342)
sa=2(1008)
sa=2016 cm²
Step-by-step explanation:
6x-11+5x+70=180
11x+59=180
11x=121
x=11.
hope this helps you.
J = M + 2
J + M = 32
(M + 2) + M = 32
2M + 2 = 32
Subtract 2 from both sides
2M = 32
Divide by 2 on both sides
M = 16
J = 18
