Answer:
40 cm²
Step-by-step explanation:
A = 2(lw + lh + wh)
= 2(4×2 + 4×2 + 2×2)
= 2(8 + 8 + 4)
= 2×20
= 40 cm²
Answer:
40cm^6
Step-by-step explanation:
surface area of this box
=2(lw+lh+wb)
=2(2×4+4×2+2×2)cm^6
=2(8+8+4)cm^6
=2×20cm^6
=40cm^6
Answer:
Step-by-step explanation: plug 1/5 in for the "n", plug 6 in for the "y" and plug -3 in for the "c". This gives you 5 x 1/5 which equals 1. So now you have 1 times 6 which equals 6. Lastly you subtract 2(-3) which is -6. This results in 6 - (-6) which equals 12.
B) 139.5 in²
C) 166 in²
D) 171 in²
Answer:
B)139.5
Step-by-step explanation:
Right-angled triangle formula A=ab/2 so find the area of both triangles left side: 2*9/2=9 right side 5*9/2= now find the area of the rectangle 9*12= add all them together 9+22.5+108=139.5
