What's us the volume. first answer get brainliest answer​

200+90 =290 m^3

Step-by-step explanation:

Find the volume of the box on the bottom

V = l*w*h

V = 8*5*5 = 200 m^3

Find the volume of the box on the top

V = l*w*h

V = 3*6*5 = 90 m^3

Add the volumes together to get the total volume

200+90 =290 m^3

290m^3

Step-by-step explanation:

the rectangular prism on top: 3mx6mx5m = 90m^3

the rectangular prism on bottom: 5mx5mx8m = 200m^3

add both: 200m^3+90m^3 = 290m^3

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
