Answer:
175
Explanation:
the formula of triangular prism is
v = 1÷2( b×h×l)
base (b) =5.1cm
height( h) = 6.9
length ( l) = 9.9
v =1÷2 ( 5.1 × 6.9× 9.9 )
v = 174.19 cm^3
so th closest will be 175cm^3
hey! so it's basically an "estimate" meaning that you can round all the measurements up to the nearest whole number. and since finding the prism's volume is l*h*w divided by 2, i did 7*5*10 and got 350. half of 350 is 175 which is the volume of the prism :)
