Answer:
b = 13
Explanation:
(3)(8)=11+b
Step 1: Simplify both sides of the equation.
(3)(8)=11+b
24=11+b
24=b+11
Step 2: Flip the equation.
b+11=24
Step 3: Subtract 11 from both sides.
b+11−11=24−11
b=13

<u>The Volume of a Rectangular Cuboid</u>
In a rectangular cuboid, all angles are right, and the opposite faces are equal.
The volume of a cuboid of dimensions a,b,c is:
V=a.b.c
The rectangular box is made of wood with externals dimensions of 25 cm by 20 cm by 15 cm.
The external volume of the box is:
The walls of the box are 0.5 thick each, this means that the internal dimensions are 1 cm less than the external dimensions, including the lid.
Thus the internal volume is:
The volume of the wood used is the difference between the external and the internal volumes:
The volume of the wood used is
