Answer:
A. 232 in²
B. 216 in²
Step-by-step explanation:
A. Box A is a cuboid/rectangular prism.
Surface area of box A = 2(LW + LH + WH)
L = 10 in
W = 2 in
H = 8 in
Surface area = 2(10*2 + 10*8 + 2*8)
= 2(20 + 80 + 16) = 2(116)
Surface area = 232 in²
B. Surface area of B = surface area of cube
Surface area of cube = 6s²
s = 6 in
Surface area = 6(6²)
= 6(36)
= 216 in²
Answer:
for every 5 boys there are b girls
Step-by-step explanation:
that's how u read ratios, for every x there are y amount of something else. portions is how we'll describe it!!
X-y = 0.7-------------(1)
x+y = 1-------------(2)
Solve simultaneously.
2x=1.7
x=1.7/2 ----- (place inside equ(1)
get y
