What is the surface area of this rectangular prism? 5 ft 4 ft 12 ft

givi [52]

Answer:

256 ft²

Step-by-step explanation:

$SA=2(lw+lh+wh)$ where l is length and w is width and h is height

Plug in the given information

$SA=2(5*4+5*12+4*12)\\SA=2(20+60+48)\\SA=2(80+48)\\SA=2(128)\\SA=2(128)\\SA=256$

Therefore, the surface area of the rectangular prism is 256 ft².

I hope this helps!

Gcf of -15xyz, -55xy²,- 55yz

GalinKa [24]

Answer:

-5y

Step-by-step explanation:

15 = 3×5

55 = 5×11

-15xyz = -1 × 3 × 5 × x × y × z

-55xy² = -1 × 5 × 11 × x × y²

-55yz = -1 × 5 × 11 × y × z

HCF = multiply all common factors with the lowest power amongst all 3 expressions

HCF = -1 × 5 × y = -5y
