Answer
The volume is 128 centimeters cubed.
The surface area is 160 centimeters squared.
Work Step by Step
$V=4\times4\times8$
$V=128$
The volume is 128 centimeters cubed.
For surface area, we need to calculate the area of the long rectangular sides and the two square sides.
Long rectangular sides:
$A=8\times4$
$A=32$
The area of a long rectangular side is 32 centimeters squared.
Square side:
$A=4\times4$
$A=16$
The area of the square side is 16 centimeters squared.
The object has two square sides and four long rectangular sides.
$4(32)+2(16)=160$
The surface area is 160 centimeters squared.
