Answer:
-4
Step-by-step explanation:
All faces are rectangles.
Each two opposite faces are congruent and have the same area.
Two faces measure 20 cm by 7 cm.
Two faces measure 20 cm by 15 cm.
Two faces measure 15 cm by 7 cm.
total surface area = 2 * 20 cm * 7 cm + 2 * 20 cm * 15 cm + 2 * 15 cm * 7 cm
total surface area = 280 cm^2 + 600 cm^2 + 210 cm^2
total surface area = 1090 cm^2

Answer:
12³
Step-by-step explanation:
A number in the <u>exponential form</u> has a small number on the top right of the base, looking like this, if "x" is the exponent and "B" is the base.
Bˣ
Value of an number in exponential form:
"x" is the number of time you multiply the base, "B" by itself.
Examples:
3² = 3 * 3
3⁴ = 3 * 3 * 3 * 3
5¹ = 5
The formula for the volume of a cube is V = s³; "s" is the length of one side.
If the length is 12, substitute 12 for "s".
V = 12³ Volume of cube in exponential form
Other answers:
12 x 12 x 12
This expression also gives you the volume of the cube, but it is not in exponential form. It is in expanded form, (V = l x w x h; length times width times height).
3¹²
This option switches the base with the exponent.
12
This option only gives the length of one edge.
