Question

A box has a length of (3x+2)cm, a width of 2x cm and a height of 5 cm a. What it is volume
b. what it is total surface area?​

Answer 1

Step-by-step explanation:

first volume is l×b×h=(3x+2)(2x)(5)

3x+2(10x)=30x²+20x

total surface area

SA=lb+lw+he

=(3x+2)(2x)+(3x+2)(5)+2x(5)

=6x²+4x+15x+10+10x

=6x²+29x+10=S
