Answer:
surface area: 340
volume: 400
Step-by-step explanation:
the formula for surface area is 2*LW+LH+HW
So (8.0)(5.0)+(8.0)(10.0)+(10.0)(5.0)=170 multiplied by 2
you find the volume by multiplying length times width times height
(8.0)(5.0)(10.0)=400
volume= length × breadth × height
= 8×5×10
400cm³
radius and number rotation
first and second part put 0.75, then multiply 0.75 by 2 to get 1.50, then write in the third part 1 and 1/2
hope this helps
